In triangle ABC, a=15cm, b=21cm, and m∠C=90 degree. Solve the triangle.

This is a right triangle, so for the missing side c, we get: 
\n" ); document.write( "To get the smaller angle (A), calculate: \"highlight_green%28matrix%281%2C3%2C+tan+%28A%29%2C+%22=%22%2C+15%2F21%29%29\"
\n" ); document.write( "To get ∡B, just subtract ∡A from 90o.
\n" ); document.write( "Why do the other people who responded make this problem look so complex?
\n" ); document.write( "Why would anyone want to use the law of cosines and/or the law of sines? Unless, of course, it is so requested? \n" ); document.write( "
