Sum of exterior angle is 360°. Take x as the total number of corners of the polygon. Each exterior side=360/x. Each interior angle is 180-(360/x)

If sum of interior angles is 5 times the sum of exterior angles, it also means that each interior angle is 5 times each exterior angle. This is because there is an equal number of interior and exterior angles for a polygon. 1 interior angle + 1 exterior angle = 180 5x + x = 180, x = 30, 5x = 150

<PRT = < PTR as they are isoceles triangle. Also, the total angle in a triangle is 180 degrees. So, to find one of the angle (<PRT), 180-68=112 112 divide by 2 = 56 To find <SQR, - total angle of triangle QSR is 180 degree - < QSR is 90 degree - <PRT was found above as 56 degree So, <SQR = 180-56-90=34
