Answer 1

If Angle A and Angle B are vertical angles,

what is value of x?

D. 8

If Angle A and Angle B are supplementary

angles, what is measure of

Angle B?

D. 140

Explanation:

If Angle A and Angle B are vertical angles,

what is value of x?

Vertical angles are congruent thus

40° = 5x°

5x° = 40°

(5x / 5)° = (40 / 5)°

x° = 8°

If Angle A and Angle B are supplementary

angles, what is measure of

Angle B?

Supplementary angles add up to 180° or a straight line.

180° – 40° = 140°
