Question

Angles of a quadrilateral are in ratio 3:4:4:7 find all the angles of the quadrilateral

Answer 1

sum of all angles of quadrilateral is 360°

let the multiple be x

3x+4x+4x+7x=360

18x=360°

x=20°

now , angles are

◆60°

◆80°

◆80°

◆140°

Answer 2

Answer:

Step-by-step explanation:

Let the number be x.

3x+4x+4x+7x = 360

18x = 360

X=360/18

X= 20

Ist angle = 3*x= 3*20=60

2nd angle =4*x=4*20=80

3rd angle= same

4th angle=7*x=7*20 = 140
