Homework Help: Math

Posted by House on Thursday, October 2, 2008 at 9:30pm.

Use the law of cosines to solve ABC with A=126.3, b=45, and c=62.5

I did all the work to find a but my problem is finding B

a=96.2

Sin(B)=45sin126.3/96.2
B=Sin^-1(45sin126.3/96.2)
It's not going through in my calculator
