Question

Two lines intersect to form the angles shown.

Which statements are true? Select all that apply.

A. m∠1=100°

​B. m∠3=80° ​

C. m∠3=m∠1

D. m∠2=80°

Answer 1

the answer i think it is ,is b

Answer 2

Option B and C are the correct option.

Explanation:

To solve this question we will go through each option given.

Option A. since ∠1 and angle = 100° are supplementary to each other.

∠1 + 100° = 180°

∠1 = 180 - 100

∠1 = 80° ≠ 100° Incorrect option

Option B.

∠3 and angle = 100° are supplementary angles

∠3 + 100 = 180°

∠3 = 180 - 100

∠3 = 80° Correct option

Option C.

∠3 and ∠1 are opposite angles

Therefore, ∠3 = ∠1 Correct option

Option D.

∠2 and angle = 100° are oppsite angles

Therefore, ∠2 = 100° ≠ 80° Incorrect option

Option B and C are the correct option.
