Homework Help: math-law of sins

Posted by skye on Thursday, August 2, 2012 at 10:09pm.

solve the triangle:
1. A= 61 degrees
a=8
b=21

2. A=136 degrees
a=15
b=28

3. C=115 degrees
b=12
c=7

For all of these problems I used law of sins and when I input it into my calculator I get domain error after doing sin inverse to get an angle degree. What am I doing wrong?
