Help please I need an answer really quick Which pair of angles are alternate exterior angles?
A. ∠1 and ∠8 (I think either A or B is the answer but I'm not sure)
B. ∠1 and ∠7
C. ∠2 and ∠7
D. ∠2 and ∠9
(I think either A or B is the answer but I'm not sure)

Step-by-step explanation:

Yeah that answer cool

just needed some points but try socratic

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
