You can put this solution on YOUR website!
Be sure that you draw the triangle according to the data given to you.\r

\n" ); document.write( "\n" ); document.write( "Law of Sines will allow you the equation, \"sin%28150%29%2F9.4=sin%28B%29%2F4.8\", and this lets you find the value for interior angle at point B.
