A wire is 30 inches long is bent into a triangle with sides measuring g 6 inches 11 inches 13 inches find the measure of the largest angle
Answer:
Largest angle is 94.22°
Explanation:
The sides of the triangle are given as 6 inches, 11 inches, 13 inches.
Now, we can find the respective interior angles of the triangle using cosine rule.
Thus, for the angle opposite 6 inches, let's label it A. Thus;
6² = 11² + 13² - 2(11 × 13)cos A
36 = 121 + 169 - 286cosA
36 = 290 - 286cos A
290 - 36 = 286cosA
cosA = 254/286
A = cos^(-1)0.8881
A = 27.36°
Similarly;
11² = 6² + 13² - 2(6 × 13)cos B
121 = 36 + 169 - 156cosB
121 = 205 - 156cos B
205 - 121 = 156cosB
cosB = 84/156
B = cos^(-1)0.5385
B = 57.42°
Sum of angles in a triangle is 180°
Thus;
C = 180 - (27.36 + 58.42)
C = 94.22°
Thus,largest angle is 94.22°
The sum of the internal angle of the triangle is 180 degrees. Then the measure of the largest angle is 95.22°.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
A wire is 30 inches long and is bent into a triangle with sides measuring 6 inches 11 inches 13 inches find the measure of the largest angle.
Then we know that the cosine rule is given as
[tex]\rm cos\ C = \dfrac{a^2+b^2-c^2}{2ab}[/tex]
Let the angle of the triangle be A, B, and C.
Then the first angle A will be
[tex]\begin{aligned} cos \ A &= \dfrac{6^2+11^2-13^2}{2*6*11}\\\\cos \ A&= \dfrac{36 + 121 - 169}{132}\\\\ A &= 95.22^o \end{aligned}[/tex]
And we know that the sum of the internal angle of the triangle is 180 degrees.
∠A + ∠B + ∠C = 180°
95.22° + ∠B + ∠C = 180°
∠B + ∠C = 84.78°

If a foot ball match is going to be aired at 9 hrs G.M.T Sunday. At what time and day fans located at 40 degrees east Addis Ababa would see
Answer: Sunday at 12h.
Explanation: The timezones are determined by the meridians, i.e., the longitudinal lines that crosses the Earth from pole to pole.
The initial referential is at GMT, abbreviation for Greenwich Mean Time, located at the Royal Observatory in the United Kingdom.
The Earth rotates 360° in 24 hours, so each 15° is exposed to the Sun for 1 hour. So, at each 15° we add an hour if the location is due to east or subtract an hour if the location is due to west.
Addis Ababa is located at 40°, which is in the band between 30° and 45°.
Counting from the referential, there are 3 timezones going east. So, we add 3 hours to the initial hour:
9h + 3h = 12h
And the day is the same since the difference is only 3 hours ahead.
Thus, fans located at 40° east will watch a football match on Sunday at 12h.

On your weekly hike, you discover a rock. This rock had different sediment layers. Some layers had marine fossils. Describe what type of rock it is, how it was formed, and how it can become another type of rock
Answer:Please find answers below.
Explanation:
1. Since the rock had different sediments with some of its layers containing marine fossils, then it is a Sedimentary rock which can be either shale, limestone or sandstone.
2.We can say the rock was formed the same way a sedimentary roc is formed . This happens when agents of erosion and weathering ( air, water) disintegrate a rock and carries the sediments from the source area ( in this case from the marine area)to another area usually referred to as area of deposition which over time accumulates and solidify to form a layered rock with marine fossils.
3. A sedimentary rock can either transform to an igneous rock or a metamorphic rock
From Sedimentary to Metamorphic--------> Metamorphic rocks are formed when rocks change their form which is due to pressure and temperature build up in the rocks. Now, when a sedimentary rock exerts pressure and heat within its structured layer, it can lead to a change in its structure forming a metamorphic rock.
From Sedimentary to Igneous Rock----->Igneous rocks are formed from molten magma. Now when there is a volcanic eruption around an area with sedimentary rocks, it melts the rocks and changes thier form and on cooling the rocks transforms to Igneous rock.

What is another animal that might have a larger than natural population because of human impact? Explain your reasoning.
Cows are probably an animal that is overpopulated because of the human species. This is happening because people need cows for what they can offer, such as milk or even food as a result they keep pushing the limits to get the most out of these animals.
Various animals might have a larger than natural population because of human impact; one is a domestic dog.
Through the human activities of using dogs as a pet, the population of dogs might have a larger than natural population.
The reason is simple, the demand for the dogs as pets would make humans breed dogs, thereby ensuring dogs have more births than a natural occurrence.
This is evident in a recent research survey conducted among pet owners.
It was revealed in 2017 that there are about 89.7 million domestic dogs in the United States.
This number revealed a 20 million increase in domestic dogs population compared to 68 million domestic dogs in 2000.
Hence, in this case, it is concluded that some human activities can positively impact the animal population.

The Berlin Conference established the borders of North African countries including Egypt Libya, and Sudan The landscape of these countries influenced the types of boundaries imposed by the European colonial powers
Which of the following boundary types best explains the influence of landscape on the political borders of the North African region?
Answer: e. Geometric, with straight lines, disregarding physical features or tribal cultural differences of the areas.
Explanation:
The boundaries of the nations of Africa as they are now is as a result of the European scramble for colonies on the continent. When these European powers held the Berlin Conference, they simply demarcated the continent amongst themselves by making claims based on maps.
These claims enabled them to draw up boundaries that were geometric with quite a number of straight lines which cared little for physical features or the tribes living in the area.
This is why countries like Egypt, Sudan, Botswana and Angola have straight lines in their boundaries as well as why tribes like the Tswana are in two different countries being South Africa and Botswana even thought they occupy the same area.

1. What should you do if you feel an earthquake happening?
2. Explain why a rural area might be a safer place to experience an earthquake than a large city.
3. Describe the three kinds of waves that are produced in an earthquake.
Answer:
Ans.1. If you are indoors, drop and take cover under a sturdy table or other furniture. Hold on to it and stay put until the shaking stops.
Stay clear of items that can fall and injure you, such as windows, fireplaces and heavy furniture.
Stay inside. You may be injured by breaking glass and falling objects if you run outside.
If you are at the coast, walk to higher ground away from the ocean as soon as it is safe for you to move.
If you are driving, move your car as far out of the normal traffic pattern as possible and stop if it is safe. Stay away from structures or objects that could fall on you, such as bridges, overpasses, light posts, power lines or trees. Stay inside your car.
If you are in the mountains, or near unstable slopes, be alert for falling rocks, trees or landslides that could be loosened by the earthquake.
Ans.2.Rural/Urban area: Rural areas have fewer people and fewer buildings so the size of the disaster is smaller. Distance from the epicentre: The closer a town or city is from the epicentre the more damage will be caused because of the strong seismic waves.
Ans. 3 There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.
