In triangle ABC, angle a=90, A=23Cm and b=12cm.find Angle c
\n" ); document.write( "-----
\n" ); document.write( "Use Law of Sines:
\n" ); document.write( "sin(B)/b = sin(A)/a
\n" ); document.write( "sin(B) = (b/a)sin(A)
\n" ); document.write( "Sin(B) = (12/90)*sin(23) = 0.0521
\n" ); document.write( "---
\n" ); document.write( "B = sin*-1(0.0521) = 2.99 degrees
\n" ); document.write( "-------
\n" ); document.write( "C = 180-[23+2.99] = 154.01 degrees
