The angles of quadrilateral are in the ratio 1 : 2 : 3 : 4 , then find the measures of each angle?
The ratio of angle of quadrilateral is = 1 : 2 : 3 : 4
Let, the measures of each angle be 1a, 2a, 3a, 4a
1a + 2a + 3a + 4a = 360 (As we know that, the sum of the angles of a quadrilateral is 360˚)
10a = 360
