Answer :

36°.

Since all the angles in a triangle are equal to 180°, you can find x by doing 2x+2x+6x=180.

Combine like terms and you get 10x=180. Divide both sides by 10 and you get x=18.

Sub in 18 for x at angle C and you get 2(18), which equals 36°.

Well, this is how you find the sum of angles in a triangle:

∠A + ∠B + ∠C = 180°

2x + 6x + 2x = 180°

10x = 180°

x = 180/10 = 18°

So:

∠C = 2*18° = 36°
