Answer:

159°

Step-by-step explanation:

A circle measures 360°. We can use this knowledge to find the unknown angles.

(10x + 9) + (6x - 13) + 34 + 90 = 360

Combine like terms and solve for x.

16x + 120 = 360

16x = 240

x = 15

So, we have found the value of x, and can now find m∠YZU.

10(15) + 9 = m∠YZU

m∠YZU = 159°

We can ascertain that this is the answer by plugging in x for the initial equation we created.

(10(15) + 9) + (6(15) - 13) + 34 + 90 = 360

159 + 77 + 34 + 90 = 360 It works!
