Answer:Sum of 4 interior angles is 360•. So sum of 4 correspondent exterior angles is 360•. With the ratio 1:2:3:3 we can get the exterior angles: 40, 80, 120, 120. So the answer for the measure of interior angles are: 140, 100, 60, 60. as the sum of the angles in a quadrilateral is 360° and it contains 4 angles. therefore, the measure of each angle is 360°/4= 90°.
