Answer:
45°
Step-by-step explanation:
Arc YZ is the difference between the given arcs and 360°:
126° +144° +YZ = 360°
YZ = 360° -270° = 90°
The inscribed angle (?) is half the measure of the arc it intercepts:
? = 90°/2
? = 45°
You just divide each side of the equation by three so you'll get

Edit: I believe you wrote the equation wrongly. If it was

, then you cubic root both sides and get

.
Sum of interior angles = ( number of sides -2) x 180 degrees.
Sum = (36-2) x 180
Sum = 34 x 180
Sum = 6,120 degrees.
