Question

the Angel of a quadrilateral are in the form of 1:3:6:8 .find the measurements of the angles

Answer 1

let the angle be x
x+3x+6x+8x=360
18x=360
x=20
1.x=20
2.60
3.120
4.160

Answer 2

sum of angle of quadrilaterals =360°
let the angles be 1x°:3x°:6x°:8x
1x°+3x°+6x°+8x°=360°
18x°=360°
x°=20°
first angle=20°
second angle=60°
third angle=120°
fourth angle = 160°
