I don't know math that good sorry. Hero can help tho. @Hero

Answer 3

Exterior Angle Theorem: Let ∠d represent the exterior angle of the triangle. Then the measure of ∠d is greater than the measure of ∠a and the measure of ∠d is greater than the measure of ∠c.

Answer 4

As it applies to this problem, ∠13 is the exterior angle and either ∠2 or ∠10 are the remote interior angles. In other words the measures ∠2 and ∠10 are both less than ∠13, so we can eliminate both as possible choices.

Answer 5

Which means the correct answer lies with either ∠8 or ∠9.

Answer 6

Between the two, you should be able to figure out the correct answer by inspection.
