Hello there,\r
\n" ); document.write( "\n" ); document.write( "We can use the tan function to help us find angle C.\r
\n" ); document.write( "\n" ); document.write( "Tan C = opp/adj\r
\n" ); document.write( "\n" ); document.write( " = 4/2\r
\n" ); document.write( "\n" ); document.write( " = 2\r
\n" ); document.write( "\n" ); document.write( "Angle C = tan^-1 C\r
\n" ); document.write( "\n" ); document.write( " = tan^-1(2)\r
\n" ); document.write( "\n" ); document.write( " ≈ 63.435°
\n" ); document.write( "
