Question

The angles of a quadrilateral are in the ratio 1:2:7:8.Find the angles​

Answer 1

Step-by-step explanation:

Let the angles be x, 2x, 7x, 8x respectively.

=> x + 2x + 7x + 8x = 360 [Angle sum property]

=> 18 x = 360

=> x = 20

First angle = x = 20°

Second angle = 2x = 2 × 20 = 40°

Third angle = 7x = 7 × 20 = 140°

Fourth angle = 8x = 8 × 20 = 160°
