Question

The angles of a quadrilateral are in the ratio 5:7:7: 11. Find the measure of each angle.

Answer 1

5x +7x+7x+11x = 360
30x=360
x=360/30
x=12
5x=60
7x=84
7x= 84
11x=132

Answer 2

give : the angles of a quadrilateral are in the ratio 5:7:7:11
required to be find out : the measure of each angle
solution :
let the angle be x
5x + 7x + 7x + 11x = 360
30x = 360
x = 360/30
∴x = 12°
the measure of first angle : 5x
5*12 = 60°
the measure of second angle : 7x
7*12 = 84°
the measure of third angle : 7x
7*12 = 84°
the measure of fourth angle : 11x
11*12 = 132°
