ZA and B are supplementary and vertical angles. What is m<B

A.180
B.135
C.45
D.90​

Sagot :

Answer:  90

Reason:

Vertical angles are equal to each other. Call them x. They must add to 180 degrees because they are supplementary (they are able to form a straight line).

x+x = 180

2x = 180

x = 180/2

x = 90
