Hey everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I was looking over some old pre-calculus exams and I found this rather obscure looking question.. It's about trigonometry.

You're given a triangle ABC, and the legs are a (BC),b (AC), c (AB).

You're given the lenghts of a=5, b-8, and the angle C between them is 140.

The question is, what's the length of the leg "c" and what are the other 2 degrees? :yuck:

Is that even possible??

Thx,

--Xeno
