Two supplementary angles measure (3x-54) and (2x+35) degrees. What is the value of x?

Answer 1

Supplementary angles, when added, always sum to 180 degrees. So make an equation by adding both angle’s measures and make it equal to 180

(3x—54)+(2x+35) = 180. Solve

3x+2x—54+35. = 180

5x. = 180+54–35

x. = 39.8
