Question

the angle of a quadrilateral are in the ratio 3:4:5:6the largest of these angle is?

Answer 1

Let the angles of quadrilater be 3x , 4x , 5x and 6x


3x+ 4x + 5x + 6 x = 360°

18x = 360°

x = 360° /18

x = 20°


Angles are 20×3 = 60°

20×4 = 80°

20× 5 = 100°

20 × 6 = 120°


therefore, sum of the largest angle is 120°


Hope, it helped☻☻☻☻☺☺

Answer 2

Let the angle be x.
Sum of angles of quadrilateral= 360
3x+4x+5x+6x=360
18x=360
x=20
So, the angles are-
3x= 60
4x=80
5x=100
6x=120
So the largest angle is 6x...that is 120..
Hope u'll understand....
