Question

the angle of a quadrilateral are in the ratio3:4:5:6.find the angles

Answer 1

Let,
First angle = 3y
Second angle = 4y
Third angle = 5y
Fourth angle = 6y

As we know that,

Sum of all angles of Quadrilateral = 360°

=> 3y + 4y + 5y + 6y = 360°

=> 18y = 360°

=> y = 360°/18

=> y = 20°

Hence,

First angle = 3y = 60°
Second angle = 4y = 80°
Third angle = 5y = 100°
Fourth angle = 5y = 120°

Answer 2

Answer:

Step-by-step explanation:

3x+4x+5x+6x=360°(sum of angles in a quadrilateral is 360°)

18x =360°

x =360/18

x =20°

3x=3*20=60°

4x=4*20=80°

5x=5*20=100°

6x=6*20=120°
