Question

three angle of a quadrilateral are in the ratio 2:4:5:7. find the of each of its angle ​

Answer 1

Step-by-step explanation:

Sum of the angles if a qudrilateral=360 degrees

the ratio of angles =2:4:5:7

let the angles be 2x ,4x, 5x, 7x

So 2x+4x+5x+7x=360

18x=360

x=360/18

x=20

So 1st angle =2x=2×20=40

2nd angle=4x=4×20=80

3rd angle=5x=5×20=100

4th angle=7x=7×20=140

Hope it helps
