Question

What is the value of x?

Answer 1

x = 30 degrees

Explanation:

Okay so we start by noticing that the two pointed out vertices = 180 degrees. So we have the following equation.

(x + 12) + (3x + 48) = 180

If you combine them you get:

4x + 60 = 180

Subtract 60 from both sides..

4x = 120

Divide both sides by 4..

x = 30

And there's your answer!
