The diagram shows the position
of three towns represented by
letters A, B and C.
B is 7 km from A on a bearing of 037°
C is 8 km from B on a bearing of 140°
Find the bearing of C from A.
Give your answer correct to 1 decimal place.
Answers
Answer:
56.29
Step-by-step explanation:
56.29^° is the answer
The bearing of town C from town A at the given position of the three towns is determined as 93.3⁰.
Distance of C from A
The distance of town C from town A is calculated by applying Cosine rule. The distance of town C from town A is represented by small letter "b" as shown in the image.
b² = a² + c² - 2ac[cos B]
b² = (8)² + (7)² - 2(8 x 7 x cos77)
b² = 87.81
b = √87.81
b = 9.37 km
Angle AThe value of angle A is determined by applying Sine rule as shown below;
sin A/a = sin B/b
sin A = (a x sin B)/b
sin A = (8 x sin 77)/9.37
sin A = 0.832
A = sin ⁻¹ (0.832)
A = 56.3⁰
Bearing of town C from town AThe bearing of town C from town A is determined from the sum of 37⁰ and angle A.
θ = A + 37⁰
θ = 56.3⁰ + 37⁰
θ = 93.3⁰
Thus, the bearing of town C from town A at the given position of the three towns is determined as 93.3⁰.

The students in Mr.Collin's class used a surveyor's measuring device to find the angle from their location to the top of a building. They also measured their distance from the bottom of the building. The diagram shows the angle measure and the distance. To the nearest foot, what is the height of the building?
a. 105 ft
b. 116 ft
c. 32 ft
d. 54 ft
Answers
The height of the building is approximately 105 ft.
According to the question,
We have the following information:
The angle made from their location to the building = 59°
The distance of the building from their location = 63 ft
Now, we can find the height of the building by using trigonometric function of tan.
We know that tan is equal to perpendicular/base.
In this case, perpendicular is the height of the building and base is the distance of the location from the building.
We have:
Tan 59° = Height of the building/distance of the building from the location
We know that the value of tan 59° is 1.6643.
Let's take the height of the building to be H ft.
1.6643 = H/63
H = 1.6643*63 ft
H = 104.85 ft
Now, this number can be rounded off to 105 ft.
Hence, the correct option is a.

Solve the equations
3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0
Answers
Answer:
a = 4 , b = -2
Step-by-step explanation:
3a + b = 10
2a + 4b = 0
(By using elimination method, eliminate one variable) - to get only one equation
(3a + b = 10 ) 4
2a + 4b = 0
12a + 4b = 40
(minus)
2a + 4b = 0
10a = 40
a = 40/10
a = 4
(substitute a into an equation to get b)
2a + 4b = 0
2(4) + 4b = 0
4b = 0 - 8
b = -8/4
b = -2

Answers
Answer: 112, 68, 22, 90
Step-by-step explanation:
This is fairly somewhat easy
since the adjacent side of 1 is 68 degrees
then 1 would be 112 degrees to make it supplementary to 180 degrees
angle 3 is vertical of angle 68
making it 68 degrees
angle 5 is given to be 90 degrees meaning angle 4 is inbetween
angles 3 and 5 so ( 68 and 90 ) that'll add up to 158 meaning angle 4
is 22
angle 1 = 112
angle 3 = 68
angle 4 = 22
angle 5 = 90
Simplify: (9a* - 5a'-1)+7a*
Answers
Answer:
The answer is -2a because first you multiple the number and eliminate redundant perenthese then last combine like terms and that how you get -2a

A bicycle helmet has a selling price of $50. The helmet is discounted 30% off the selling price. The sales tax rate is 6%. What is the total cost of the helmet?
Answers
Multiply by the cost of the helmet, $50
50 x 0.30 = $15, the amount of the discount.
50-15 = $35, the sale price of the helmet.
For the sales tax, again, convert to a decimal by dividing by 100 = 0.06
35 x 0.06 = 2.10, the amount of sales tax
$35 + $2.10 = $37.10, total cost with tax

Answers
Answer:
y = 25.8
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos y = adjacent/ hypotenuse
cos y = 18/20
Take the inverse cos of each side
cos ^-1 (cos y) = cos^-1(18/20)
y =25.84193276
Rounding to the nearest tenth
y = 25.8
