# I cut a triangle ABC out of a piece of paper. I found out that sinA+sinB+sinC=5/2 and a/sinA=16. What is the triangle’s perimeter?

Permeter

By sine rule for a

where

Given

and

combining [1] and [2] we get

Hence

Inserting these in [3] we get

So Perimeter

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
