Question

the angle of quadrilaterl are in the ratio 2:4:5:7 ​

Answer 1

Answer:  40,80,100,140 are angles  of quadrilateral.

Step-by-step explanation:

2:4:5:7

Let x be the common multiple.  

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

Sum of angles in a quadrilateral is 360  

 18x=360

x=20

∴ 2x=2×20=40,4x=4×20=80,5x=5×20=100,7x=7×20=140

40,80,100,140 are angles  of quadrilateral.

Answer 2

Answer:

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 =2x32x20=4O

2nd angle=4x=4x20=80 3rd angle=5x=5x20=100

4th angle=7x=7x20=140

Hope it helps
