Question

the angle of the abc taken in order are in the ratio 9:6:7:8,find the measure of all the angle of the quadrilateral

Answer 1

Answer:

Step-by-step explanation:

Let a=9x, b=6x, c=7x,d=8x

a+b+c+d=360°

9x+6x+7x+8x=360°

30x=360°

x=360/30

x=12

a= 9x= 9×12=108°

b= 6x= 6×12=72°

c= 7x= 7×12=84°

d= 8x= 8×12=96°
