Question

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

What is the value of x?

Enter your answer in the box.

x =

Answer 1

34°

Explanation:

3x - 6 + 2x + 108 + 88 = 360

5x = 360 - 190

5x = 170

x = 34°

Answer 2

34

Explanation:

If we know that these angles all add up to 360, then we can simply add up all the expressions, set them equal to 360, and solve for x:

(3x - 6) + 2x + 108 + 88 = 360

Combine like terms:

5x + 190 = 360

Subtract 190:

5x = 360 - 190 = 170

Divide by 5:

x = 170/5 = 34
