Question

I need help with geometry, finding the measures for angles, it tells me one angle is 63, another is (2x+8), and another is (x+7)

Answer 1

63, 41, and 76

Explanation:

A triangle is equal to 180 degrees. So, its angles must be equal to 180 degrees. So, we set 63+2x+8+x+7 equal to 180. Combining like terms, we get 78+3x=180. We want to isolate x, so, we subtract 78 from both sides to get 3x=102. Then we divide by 3 on both sides, x=34. Now, that we have x, we plug it into (2x+8) and (x+7). 2(34)+8= 76 and (34+7)= 41.
