Question

What is the measure of the unknown angle?

Answer 1

Answer:

x + 120 + 36 = 180 ( sum of three angles in a triangle is 180 )

x + 156 = 180

x = 180 - 156

x = 24

24 is the unknown angle

Answer 2

Step-by-step explanation:

Let unknown angle be x

So, 120°+36°+x=180 (angle sum property )

156°+x=180

x=180-156

x=24°

Therefore ,unknown angle =24°
