Use the sum-to-product formula to simplify the expression:
\n" ); document.write( "If sin 44 degrees + sin 16 degrees = sin A degrees, 0 A = how many degrees. \r
\n" ); document.write( "\n" ); document.write( "-----
\n" ); document.write( "2sin(60/2)cos(28/2) = sin(A)
\n" ); document.write( "2sin(30)*cos(14) = sin(A)
\n" ); document.write( "cos(14) = sin A
\n" ); document.write( "sin(A) = cos(90-A)
\n" ); document.write( "---------------------------
\n" ); document.write( "A = 90-14 = 76 degrees
\n" ); document.write( "--------------------------
