Exterior angle theorem

A) 83°

B) 68°

C) 97°

D)62°

A: 83°

Step-by-step explanation:

The exterior angle theorem states that the sum of the two interior angles of a triangle is equal to the exterior angle of that same triangle.

In this case, the two opposite interior angles to the exterior angle are: 52° and 31°.

Sum of them = 52 + 31 = 83°

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
