telescope is mounted on a tripod 5 ft above the ground and 20 ft from a flagpole.
\n" ); document.write( " The telescope must be rotated 54˚ from horizontal to see the top of the flagpole.
\n" ); document.write( " How tall is the flagpole?
\n" ); document.write( ":
\n" ); document.write( "This forms a right triangle, we can use the tangent of 54 degrees to find the opposite side (a) which is the flag pole
\n" ); document.write( ":
\n" ); document.write( "Tan(54) = $\"a%2F20\"$
\n" ); document.write( "a = 1.37638 * 20
\n" ); document.write( "a = 27.5276 ft
\n" ); document.write( ":
\n" ); document.write( "The telescope is 5' above the ground therefore:
\n" ); document.write( "27.5276 + 5 = 32.5276 is the height of the flag-pole \n" ); document.write( "

\n" );
