Question

The anglesof a quadrilateral are in the ratio of 2:3: 5: 8 . find the angles of quadrilateral.

Answer 1

let the angle of quadri be 2x, 3x , 5x , 8x.
2x+3x+5x+8x=360
18x              =360
x                =      360/18
x                =20
2x=2*20=40

3x=3*20=60
5x=5*20=100
8x=8*20=160

Answer 2

2x+3x+5x+8x=360
18x=360
x=20
so the angles  are 40,60,100,160
