Question

Find the measure of the listed angles below.

Answer 1

30,90

Explanation:

because it all adds up to 180

Answer 2

E and I are alternate interior angles, therefore are congruent

• m∠E = m∠I = 60°

E and F are complementary, therefore add to 90°

• m∠F = 90° - 60° = 30°

H and I supplementary, therefore add to 180°

• m∠H = 180° - 60° = 120°
