Question

# If the sides of a triangle are in the ratio then greatest angle is

Hint:

### In this question, we have to find the angle of the greatest angle. As c is the greatest side so angle C is the greatest angle. As we know the sides ratio, so using the cosine formula we will find the angle of the greatest side.

## The correct answer is:

### As the ratio of the sides is

a= x, b=y, c =

c is the largest side, so, C is the largest angle.

So, the angle of the greatest angle is 120.
