Question

. The four angles of a quadrilateral are in the ratio 2:3:5:8. Find the angles
​

Answer 1

the ratio of angles of a quadrilateral are 2:3:5:8

let the 4 angles be 2x, 5x, 3x, and 8x

we know, the sum of 4 angles of quadrilateral is 360°

there fore 2x+3x+5x+8x=360°

18x=360°

x=20°

the angles are

2x=2×20=40°

3x=3×20=60°

5x=5×20=100°

8x=8×20=160°
