4x-10 3x-22 3x+3 find x when its an equilateral triangle?

x=15.1°

Step-by-step explanation:

Angles in an equilateral triangle adds up to 180°

(4x - 10) + (3x - 22) + (3x + 3) = 180

Putting the like terms together;

4x + 3x + 3x - 10 - 22 + 3 = 180

10x - 29 = 180

10x = 180 - 29 = 151

x = 151/10 = 15.1°
