# How to calculate theta from tantheta

tan theta = 0.107
Therefore theta = 6.14 degrees

How do I come to this conclusion using a calculator?

Thanks

on you calculator, there must be a button saying tan$$^{1}$$. After pushing that, enter the tanthetha value, and you will get the angle.

opps the button is tan$$^{-1}$$

I thougt that was it, but my calculator returns .016594434 when tan$$^{-1}$$(.107) is entered

It looks like your calculator is set to radians instead of degrees.
