equation: 8x^3 + 2 = 26
brandon's solution:
step 1: subtract 2 from each side.
step 2: divide each side by 8.
step 3: divide each side by 3.
a. step 1
b. step 2
c. step 3
d. all of the inverse operations were correct

answerim :

n

step-by-step explanation:

im not sure but my dad knows

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 a. q=6,r=6√2
