# Thread: How do i find the sides of this triangle?

1. ## How do i find the sides of this triangle?

Heres the question:

On the banks of a river, surveyors marked locations A, B, and C. The measure of angle ACB=70 degrees and the measure of angle ABC=65 degrees. Which expression shows the relationship between the lengths of the sides of this triangle?

That means i need to find the sides of the triangle right? How would i do this?

Which expressions indeed??

It would help if you included them.

I'm guessing you'll need the sine rule

$\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}$

3. 1)ab< Bc< Ac

2)bc< Ab< Ac

3)bc< Ac< Ab

4)ac< Ab< Bc

4. In any triangle, the largest side will be opposite the largest angle and the smallest side will be opposite the smallest angle. Can you see the answer now?
