### Need a kickstart in the right direction

I am working with this angle as shown: http://www.csgnetwork.com/righttri.gif and using this calculator as a check: http://www.csgnetwork.com/righttricalc.html

I have the following:

A 49.25 degrees
B 40.75 degrees
C 90 degrees

a
b 204.8ft
c

Please forgive me but it's been a very long time since I've done trig. I've been looking online everywhere and cannot find an answer for dummies. I am using protractor degrees and I'm not sure if they are referred to degrees or radiants so sorry. I need to find the length of a and c and put this into Excel. I thought I had this figured out but when I went to plot out the shapes on graphing paper everything came out wrong. HELP PLEASE!!! THANKS!!

Have you tried using The Law of Sines?

Thanks. I got what I needed for the equation from the first example then figured out how to convert it in excel.
