# Math Help - [SOLVED] Trying to understand this website's example

1. ## [SOLVED] Trying to understand this website's example

I was looking over some websites that showed examples of optimization problems in hopes of getting better at them.

Here's the site.
http://tutorial.math.lamar.edu/Class...imization.aspx

I'm referring to example 5.

It says, "using basic right angle trig we can see that: L1 = 8secx and L2 = 10cscx"

How did they figure that out?

2. Nevermind... got it.
