Question

angles of quadrilateral ratio 3: 4:5:6 . find the value of Angles

Answer 1

Let the angles are 3x, 4x, 5x and 6x

Then,

As we know that the sum of angles of a quadrilateral is 360°


Then,

3x+4x+5x+6x=360

18x=360°

x=360/18

x=20


Then,

Angles are =3(20)=60

4(20)=80

5(20)=100

6(20)=120




I hope this will help you

Answer 2

In a quadilateral the angles add up to 360

Let's call the angles  3x , 4x , 5x and 6x

Then:
3x+4x+5x+6x=360→
18x=360→x=20

Then the angles are  60 , 80 ,100 and 120.
(because 3⋅20=60 etc)
