Question

PQRS is quadrilateral whose angles are in the ratio 1:3:7:9. Find the measure of each angle.

Answer 1

Step-by-step explanation:

do

1x+3x+7x+9x= 360

20x =360

x=360/20=18

now put value of x in 1x+3x+7x+9x

so 18,54,126,162

answer

Answer 2

Step-by-step explanation:

Total angle of a quadrilateral = 360°

Ratio = 1:3:7:9

= 1x , 3x , 7x, 9x

= 1x + 3x + 7x + 9x = 360°

20x = 360°

x = 360/20

= 18°

1x = 18°

3x = 18*3

= 54°

7x = 7*18

= 126°

9x = 18*9

= 162°
