Question

Need help answering this math question. It is MULTIPLE CHOICE. Which ones are correct?

A. m∠1 = m∠6
B. m∠2 = m∠6
C. m∠1 + m∠6 = 180°
D. x = 90°
E. x = 120°

Answer 1

Answer: B. and E.

Explanation:

B. is correct because m∠2 = m∠6 are alternate interior angles and alternate interior angles formed by parallel lines and a transversal are congruent.

E. x= 120°

m∠2 = m∠6=75°

∠6+x-15=180°

75°+x-15°=180°

60°+x=180°

x=180°-60°

x=120°
