The find the measure of the four angles of a quadrilateral if they are in the ratio 3 :5: 7: 9

Answer» HEY mate I HOPE this will help you

let the four angles be a,b,c,d so a = 3x , b = 5x , c is 7x and d is 9x

sum of all angles in a quadrilateral is 360°

so 3x + 5x + 7x + 9x = 360°
24x = 360°
x = 360.24 = 15

from this a is 45
b is 75
c is 105
d is 135
