Question

The angles of a quadrilateral are in ratio 10:7:8:11. Find all the angles of the quadrilateral.​

Answer 1

we know that sum of all sides of quadrilateral is 360°.

let the required no. be "x".

then,

10x + 7x + 8x + 11x = 360°

36x =360°

x = 360°/36°

x = 10°

now,

angle 1 = 10x

10x10 =100°

angle 2 = 7x

7x10 = 70°

angle 3 = 8x

8x10 = 80°

angle 4 = 11x

11x10 = 110°
