Question

angels a b c d = 3:4:5:6 find all the angles of the trapezium

Answer 1

for angles ... u hav writtren angels

Answer 2

Hi ,

a , b , c and d are angles of a

Trapezium ,

a : b : c : d = 3 : 4 : 5 : 6

Let

a = 3x ;

b = 4x ;

c = 5x ;

d = 6x :

We know that ,

Sum of the 4 angles in a quadrilateral

= 360°

3x + 4x + 5x + 6x = 360°

18x = 360

x = 360/18

x = 20

Therefore ,

Required angles are ,

a = 3x = 3 × 20 = 60°

b = 4x = 4 × 20 = 80°

c = 5x = 5 × 20 = 100°

d = 6x = 6 × 20 = 120°

I hope this helps you.

:)
