Homework Statement
I don't understand how to get CE.
Homework Equations
Trigonometric identities (maybe)
The Attempt at a Solution
[/B]
First, I start with the cosine rule
CB^2 = AC^2 + AB^2 - 2 AC AB cos α
(CE/sin(β))^2 = (CE/sin(α))^2 + L^2 - 2 (CE/sin(α)) L cos α
which is going to be a quadratic equation and it's hard to obtain what CE is (using this method)
Please help
