Question

The measures of a quadrilateral are in the ratio 2 : 4 : 5 : 7.Find the measure of each of it's angles ​

Answer 1

Answer:

frist assume 2:4:5:7as2x,4x,5x,7x.

and now add it .it will become 18x=360(by using property of quadrilateral)

40° ,80°,100°,140°

Answer 2

Step-by-step explanation:

let the ratio's be 2x+4x+5x+7x

2x+4x+5x+7x=360°

18x=360°

x=360°/18

x=20

substitute the value of x

2=2(20)

=40

4=4(20)

=80

5=5(20)

=100

7=7(20)

=140

the angles are 40°,80°,100°,140°.
