Answer: C
Explanation:
I'll explain why.
The sum of the angles in a triangle must be equal to 180ยบ. We already know 2 of the 3 angles, therefore, we can make an equation to find x.
The sum of the angles (x+36+120) must be equal to 180 (=180)
x+36+120=180
Combine like terms
x+156=180
Subtract 156 to isolate x
x=180-156
x=24
