Answer:
The measure of angle B is 54°. The measure of angle A is 51°. The measure of angle AFE is 47°.
According to exterior angle theorem: It a triangle
Exterior angle = Sum of opposite interior angles
In triangle BED,
The measure of angle B is 54°.
In triangle ABC,
The measure of angle A is 51°.
In triangle AEF,
Using angle sum property,
Therefore the measure of angle AFE is 47°.
Answer:
less than
Step-by-step explanation:
The answer is (-10) - 9= -19
Answer: C, D
Step-by-step explanation:
31 - use the Pythagorean theorem to find the distance
![a^{2} +b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D)
a = 45
b = 28
plug in values
![45^{2} +28^{2} =c^{2} = 2809](https://tex.z-dn.net/?f=45%5E%7B2%7D%20%2B28%5E%7B2%7D%20%3Dc%5E%7B2%7D%20%3D%202809)
c = 53
answer choice C
32 - non linear functions are functions that aren't straight. if a function has anything besides a constant or an x variable to the power of 1, it is not linear
A - this is linear because -18 is a constant
B - this is linear because it only contains constants and an x variable to the power of 1
C - this is linear because it only contains an x variable to the power of 1
D - this is not linear because the x variable is on the bottom of the fraction, so x is to a power of -1
answer choice D
