Question

The angle measures of a triangle are (x + 15), (2x - 20), and 2x. What are the actual angle measures of the triangle? I don't know how to solve this question. Please help explain how to get the answer.

Answer 1

The sum of the interior angles of a triangle is 180 so to find x your equation would be (x+15)+(2x-20)+(2x)=180...once you solve this equation x should be 37...and now you just plug in 37 for x and solve for the angle measurments....(37+15)=52....(2(37)-20)=54....2(37)=74
