    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}

    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?
