What is the measure of
stepan [7]

Answer:

Angle A is 37 degrees, Angle B is 82 degrees, Angle C is 61 degrees

Step-by-step explanation:

Exterior angles are the supplement of interior angles, so subtract 143 from 180 to find Angle A.

180 - 143 = 37

All angles add up to 180.

37 + 61 = 98

180 - 98 = 82

Angle B is 82 degrees.

Hope this helped. :)

How do I solve this problem
guapka [62]
You first subtract 1/5 from both sides
3/4-1/5 = 11/20 
3/2x=11/20

now you multiply 2/3 on both sides since you have to get x

11/20 * 2/3 
x = 11/30
