Question

the angels of a quadrilateral are in the ratio 2 : 4 : 5 : 7 . find the angels.​

Answer 1

Answer:

let the angle be 2x+4x+5x+7x=360 degree as the sum of angle in qualatireal

Step-by-step explanation:

18x=360 therefore answer it value of x = 20 so

2x = 2×20=40

4x=4×40=150

5x=20×5 =100

7x=20×7=140

Answer 2

Step-by-step explanation:

we take a viable x

Then, we let 1st angle=2x

2nd angle=4x

3rd=5x

and 4th=7x

now '

we know that sum of all the angles of a quadrilateral =360 degree

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

18x=360

hence,x=20 degree

2x=40 degree

4x=80

5x=100

7x=140
