    [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?
