Question

in a quadrilateral angle A B C D the angle A B C D the are in the ratio 1:2:4:5 find the ratio of each angle of ABCD

Answer 1

letting girls pee x, 2x,4x,5x
sum of quadrilateral angles=360
So,
X+2x+4x+5x=360
12x=360
X=360/12
X=30
So, angles will be =
1×30=30
2×30=60
4×30=120
5×30=150

Answer 2

sum of angles of a quadrilateral =360°
X + 2X + 4 X +5x= 360°
12X = 360°
X = 30°
A=x=30°
B=2x=30×2=60°
C=4x=4×30=120°
D=5x=30×5=150°
