As it has an angle that is 90 degrees it is a right-angle triangle and therefore cosine, sine and tangent can be used to find the angles.\r
\n" ); document.write( "\n" ); document.write( "As the side that is 6 long is adjacent to the known angle of 30 you can use cosine:\r
\n" ); document.write( "\n" ); document.write( "(Cosine (angle) = adjacent/hypotenuse\r
\n" ); document.write( "\n" ); document.write( "so:\r
\n" ); document.write( "\n" ); document.write( "Cos 30 = 6/h where h is the unknown hypotenuse.\r
\n" ); document.write( "\n" ); document.write( "reaarange by moving the h to the other side by multiplying both sides by h:\r
\n" ); document.write( "\n" ); document.write( "Cos 30 x h = 6\r
\n" ); document.write( "\n" ); document.write( "and then move the Cos 30 by dividing both sides by Cos 30:\r
\n" ); document.write( "\n" ); document.write( "h = 6/ Cos 30\r
\n" ); document.write( "\n" ); document.write( "now calculate using the cos function:\r
\n" ); document.write( "\n" ); document.write( "h = 6.93\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
