Question

9) In the given figure, if the angles a and b are in the ratio 2 : 3, then find the angle c



​

Answer 1

Answer:

Let the third angle x

The first angles are 2x, 3x

So the equation will be

2x+3x+x=180degree (angle sum property)

6x=180

X=180/6

X=30

1st angle is 2x=2*30=60degree

2nd angle is 3x=3*30=90degree

Now the third angle is 30degree
