Question

Two lines intersect to form the angles shown.

Which statements are true?

Select each correct answer.

A. m∠2=80°

B. m∠1=100°

C. m∠3=m∠1

D. ​m∠3=80°

Answer 1

Answer: The answer is -

m∠3=80 degree

sm∠3=m∠1

Explanation:

When two lines intersect, the opposite angles are equal. They are called vertical angles. That means for this problem: would be true:

m∠1 = m∠3

100° + m∠3 → m∠3 = 80°
