Answer:
it would be an acute angle because it is less than 90
Answer:
It would be a right triangle
Step-by-step explanation:
A triangle must always have 3 angles that add up to 180°.
So if two angles are 45°, then the last angle has to add along with the 45° angles to equal 180°.
If you multiply 45 × 2 (since there are two angles that are 45°), you get 90, which is half of 180.
Also a 90° angle is a right angle, which would help you out with remembering.

The 4th term as a G.P is 384 and
3rd term is 96 find the first term.
Answer:
first term is 6
Step-by-step explanation:
MULTIPLY BY 4
1) 6 (1st term)
2) 6x4 = 24 (24 is the second)
3) 24 x 4 = 96 (96 is the 3rd)
4) 96 x 4 = 384 (384 the 4th)
3. Priya says, "I know everything about a right triangle with a 30 degree angle and a hypotenuse with length 1 cm. Here look." The other angle is 60 degrees. The leg adjacent to the 30 degree angle 0.866 cm long. The side opposite the 30 degree angle is 0.5 cm long. Han asks, "What would happen if a right triangle with a 30 degree angle has a hypotenuse that is 2 cm instead?" Help them find the missing angles and side lengths in the new triangle. Explain or show your reasoning.
Answer:
1) The measure of the third angle is 60°
2) The length of the opposite side to the angle 30° is 1 cm
3) The length of the opposite side to the third angle 60° is approximately 1.732 cm
Step-by-step explanation:
1) The given parameters are;
The known angle of a right triangle = 30°
The length of the hypotenuse = 2 cm
Given that the triangle = A right triangle, with one of the interior angles = 90°, we have;
The measure of the third angle = 180° - 90° - 30° = 60°
The measure of the third angle = 60°
2) We have that sin(30°) = 0.5 = (The length of the opposite side to the angle 30°)/(The length of the hypotenuse side)
0.5 = (The length of the opposite side to the angle 30°)/(2 cm)
∴ The length of the opposite side to the angle 30° = 2 cm × 0.5 = 1 cm
The length of the opposite side to the angle 30° = 1 cm
3) Similarly, the length of the opposite side to the third angle 60° = sin(60°) × (The length of the hypotenuse side)
∴ The length of the opposite side to the third angle 60° = (√3)/2 × 2 cm = √3 cm
The length of the opposite side to the third angle 60° = √3 cm ≈ 1.732 cm

Answer:
Option C
Step-by-step explanation:
Since it's draining, it means it must start at a certain value and end at a maximum of 0 since water cannot ever be less than 0. Since it's original amount is 40, it can only start draining from 40 and end at max 0 hence 0 ≤ y ≤ 40

Mrs. Conley asks her class what kind of party they want to have to celebrate their excellent behavior. Out of all the students in the class,
5
55 want an ice cream party,
7 77 want a movie party,
10 want a costume party, and the rest are undecided.
If 20% percent want an ice cream party, how many students are in the class?
Step-by-step explanation:
let 'x' represent the total number of students in the class
5 = 20% of x
0.20x = 5 divide both sides by 0.20
x = 25 students
there are 25 students in the class.

Use the elimination method to solve the system of equations. Choose the correct ordered pair
-x+5y=-4
4x+3y=16
Will give brainiest.
Answer:
x = 4 and y = 0
Step-by-step explanation:
Using the elimination method:
4(-x + 5y=-4) --> -4x + 20y = -16.
Now we add -4x + 20y = 016 and 4x + 3y = 16. This gives us 23y = 0 or just y =0.
Now we can find x by plugging in y.
-4x + 0 = -16.
Divide by -4 on both sides -> x = 4.
If you want to double check you can plug your values into -4x + 20y = -16.
-4(4) +20(0) = -16.

which ordered pair is a solution of the equation: 2y=7x-3
only 2,4
only 3,9
both 2,4 and 3,9
neither
Answer:
It is only 3,9.
Step-by-step explanation:
You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:
2(9) = 7(3)-3
18= 18
The answer is (3,9).

At cultutral arts day each session lasts 4/5 hours. The principal has set aside 3 hours for the sessions. Determine the number of sessions that can be sheduled for each student
Answer: 3.75
Step-by-step explanation:
The following can be gotten from the question:
Time taken for each session = 4/5 hours
Total time set aside by principal = 3 hours
The number of sessions that can be sheduled for each student will be:
= Total time set aside by principal / time taken for each session
= 3 hours / 4/5 hours
= 3 × 5/4
= 3.75
How to do this question plz answer
Step-by-step explanation:
a) m∠AOB = 360°/8 = 45°
Internal angle is 360°, divided by 8 sides of octagon
b) m∠ABC = 2m∠ABO
m∠ABO = m∠BAO = 1/2(180° - 45) = 1.2(135°)
m∠ABC = 2*1/2(135°) = 135°
Answer:
a) 45
b)135
Step-by-step explanation:
[tex]In\ order\ to\ find\ the\ sum\ of\ all\ the\ interior\ angles\ of\ a\ polygon\ with\ sides\ n,\\S=180(n-2)\\Here,\\As\ the\ figure\ is\ a\ regular\ octagon\ ,\\The\ sum\ of\ all\ of\ its\ angles\ = 180(8-2)\\=180*6=1080\\Hence,\\Given\ that\ it\ is\ regular\ or\ that\ all\ of\ its\ angles\ are\ equal\ in\ measure.\\Hence,\\b) Angle\ ABC=1080/8\\=135\\As\ it\ is\ regular\ , the\ diagonals\ passing\ through\ the\ center\ bisects\ the\ respective\ angles.[/tex]Hence,
[tex]Angle OAB=135/2 = 67.5\\Angle ABO=135/2=67.5\\Through\ the\ angle\ sum\ property\ of\ a\ triangle\\Angle OAB+AngleABO+Angle AOB=180\\67.5+67.5+AngleAOB=180\\135+AngleAOB=180\\Angle AOB=180-135\\=45[/tex]
find the value of x
Answer:
x = 12
Step-by-step explanation:
In a pair of intersecting lines the vertically opposite angles are equal.
[tex] \longrightarrow [/tex] (6x + 7)° = (8x - 17)°
[tex] \longrightarrow [/tex] 6x + 7 = 8x - 17
Subtract 8x + 7 from both sides:
[tex] \longrightarrow [/tex] 6x + 7 - (8x + 7) = 8x - 17 - (8x + 7)
[tex] \longrightarrow [/tex] (6x - 8x) + (7 - 7) = (8x - 8x) + (-17 - 7)
6x - 8x = -2x:
[tex] \longrightarrow [/tex] -2x + (7 - 7) = (8x - 8x) + (-17 - 7)
7 - 7 = 0:
[tex] \longrightarrow [/tex] -2x = (8x - 8x) + (-17 - 7)
8x - 8x = 0:
[tex] \longrightarrow [/tex] -2x = -17 - 7
-17 - 7 = -24:
[tex] \longrightarrow [/tex] -2x = -24
Divide both sides by -2:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{-2x}{-2} = \dfrac{-24}{-2} [/tex]
[tex] \sf \dfrac{-2}{-2} = 1 [/tex]
[tex] \longrightarrow [/tex] [tex] \sf x = \dfrac{-24}{-2} [/tex]
[tex] \sf \dfrac{-24}{-2} = 12 [/tex]
[tex] \longrightarrow [/tex] x = 12
