The angles p,q,r,s of a quadrilateral are in the ratio 1:3:7:9 i]find the measure of each angle

Given the sum, the ratio of angle is 1:3:7:9. That is 20 parts is 360 degree (sum of the interior angles of a quadrilateral is 360 degrees). 1 part = 360/20=18 degrees. So the angles are
18, 3x18, 7x18, 9x18 that is 18, 54, 126 and 162 degrees
