Question

Three angles of the quadrilateral are in ratio 1:2:3.The sum of smallest and the greatest is 180°.find all the angles of quadrilateral​

Answer 1

Let the 3 angles be x, 2x and 3x

Given that x + 3x = 180

4x = 180

x = 180/4 = 45°

So the three angles are 45°, 90° and 135°

and the fourth angle = 360 - (45*90+135) = 360 - 270 = 90°
