Triangles AABC and APQR are given. AABC = APQR by SAS. If IZABC = 12x + 2, mzPQR = 142 - 2x, AB = 5y - 7, and PQ = 3y - 1, then which of the following statements are true? Select all that
apply.

first one because it can't have a fraction in it

step-by-step explanation:

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

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°.

the answer is -1 1/5, also a
