Problem Solving (PS) | Re: In the figure above, p + q =

Since the sum of all the exterior angles of a polygon is 360, we note that 115, p, and q are measures of three of the four exterior angles of the quadrilateral, while the last exterior angle measures 180 - 80 = 100 degrees. We can now set up the following equation:

115 + p + q + 100 = 360

215 + p + q = 360

p
