Question

the angles of a quadrilateral are in the ratio 3:4:5:6.find them

Answer 1

Let ratio COEFFICIENT BE X
Then ATQ:-
3x+4x+5x+6x=360
18x=360
x=20
angles are 60°,80°,100°,120°

Answer 2

let the angle be x

3x +4x + 5x + 6x = 360

18x = 360

x = 360/18

x = 20

then

3×20 = 60

4×20 = 80

5× 20 = 100

6×20 = 120
