Answer» ratio of the first angle = xratio of the second angle = 2xratio of the third angle = 3xratio of the fourth angle = 4xNow sum of all the angles is 360so we can write it as x+2x+3x+4x = 360 10x = 360 x = 360/10 x = 36first angle is 36 second angle is 2x = 72third angle is 3x = 108fourth angle is 4x = 144hence the angles of the quadrilateral are36,72,108,144. The angles are 36, 72, 108, 144. |
