Answer
p = 90 degrees
q = 122 degrees
Work Step by Step
1. solve for q:
58 * 2 = 116
circle --> 360 degrees
360 - 116 = 244
Half of 244 = q
244 / 2 = 122
q = 122 degrees
2. solve for p:
the sum of the angles of a quadrilateral = 360 degrees
p = 360 - 58 - 90 - q
p = 360 - 58 - 90 - 122
p = 90 degrees
