Find the value of x. Then find the angle measures of the triangle?

Answer 1

IF 3 angles are x+10, x-5, and 2x+20

then add them up and set equal to 180

all 3 angles of any triangle sum to 180 degrees

x+10+x-5 + 3x+20 = 180

5x = 180-10+5-20 = 155

x = 155/5 = 31

the 3 angles are 41, 26, and 113 degrees

31+10 = 41

31-5 = 26

3(31)+20 = 93+20 = 113
