One of the other angles is 72. Vertically opposite angles are equal.
Two angles that are side by side on this arrangement are supplementary.
That means they are to 180
x + 72 = 180
x = 180 - 72
x = 108
Answer
the for angles are
72 + 72 + 108 + 108
Area of a sector: 1/2r^2 theta
Need theta
Let x be theta for now
42.25 pi = 1/2r^2x
84.5pi = r^2x
84.5pi = 169x
x = 84.5pi/169 = roughly 1.57 in radians
Radians => degrees is 1.57 * 180/pi or roughly 90.
