Question

In a quadrilateral abcd if angle=60°and angle b:c:d are 2:3:7find angle d is ___

Answer :-

Let the angles of the quadrilaterals are A = x, B = 2x, C = 4x and D = 5x

We know, sum of all angles of a quadrilateral = 360° A + B + C + D = 360°

x + 2x + 4x + 5x = 360°

12x = 360°

x = 360°/12 = 30°

Therefore,

A = x = 30°

B = 2x = 60°

C = 4x = 120°

D = 5x = 15°
