The measure of an angle is 12° less than twice the measure of its supplement. what is the measure of the angle?

28°
64°
34°
116°

Here is the equation you should use: x + 2x - 12 = 180    
You will be solving for x. 

Combine like terms then add twelve to both sides of the equation.

3x = 192

Divide by 3 on both sides of the equation. 

x = 64

Now, plug 64 in the equation for x. 

2(64) - 12 = 116

Ithink the answer will be d yes
