Can anyone help me with pre-Calc?

I have a pre-calculus question… So if someone out there is smart with math could you give me a lil help… the question is…

find the reference angle of theta ‘ … theta= -2.2

I took -2.2 and timed it by 180 over pi which equals -126.05 degrees does that mean the reference angle is 54 degrees.. ?

(I cant really explain wut I did any other way… hmmm hopefully someone understands)

im not 100% positive it did this rite… so if your a calculus freak or you know what your doing could you give me a little bit of help with this homework question..

=] thanks everyone…
