which method should I use to find the missing side length of the triangle? the following methods can include Law of Sines, Law of Cosine, SOH-CAH-TOA, and Pythagorean Theorem. After picking a method thats applicable to solve for the missing side length round your answer to the nearest tenth! ​

step-by-step explanation:

1st step

add 3+6

=9

multipy 9*3

=37

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°.
