Question

In the diagram below, lines h and s are parallel. If the m∠2 = 70°, what is the angle measurement of m∠1?

a. 70
b. 130
c. 7
d. 110

Answer 1

D. 110°

Explanation:

∠1 and ∠2 are supplementary meaning they add up to 180°.

m∠1 + m∠2 = 180°

m∠1 + 70° = 180°

m∠1 = 110°

Answer 2

Geometry

The answer is D because the two sides add up to 180.
