## 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
