Basic Trig

This isn't my homework, it's a question

Hypotnous = H
Adjacent = Ha
Opposite =Ho


H = 15
Ho = 4
Ha = 6

What is the Theta? - How do I find the theta from the tiny number I get when I do the cosign\sin shit?

For added pleasure. How do I do reverse sin\cos\tangent- a.k.a Arc sin\cos\tan

well on my calculator there is a sin BUTAN and above it written in yellow is sin^-1, this means if i press shift then sin it puts upon the calculator

sin^-1 on the screen, I then put the number I want to sin^-1 and press enter and out pops the answer in degrees, or radians, whichever setting you have
