Answer: 11.375°

Explanation:

55 + (4x + 17) + (4x + 17) = 180° Set up equation

4x + 4x + 55 + 17 + 17 = 180° Commutative Property of Addition

8x + 89 = 180° Combine like terms

8x = 91° Subtract 89 from both sides

x = 11.375° Divide both sides by 8

Not entirely sure about this one; you might have to round the answer.
