\"Altitude\"? Perhaps you mean \"angle of elevation\"
\n" ); document.write( "The angle of elevation is the angle (A) formed between the ground and the line-of-sight from the end of the rod's shadow to to top of the rod.
\n" ); document.write( "The given ratio of $\"1%3Asqrt%283%29\"$ is the tangent of the angle (A) of elevation. To find the angle, take the inverse tangent, often written as $\"Tan%5E%28-1%29%28A%29\"$ , (the angle whose tangent is A) which can be found on your calculator.
\n" ); document.write( " $\"Tan%5E%28-1%29%281%2Fsqrt%283%29%29+=+30\"$
\n" ); document.write( "The angle of elevation of the sun is 30 degrees.
\n" ); document.write( "The altitude of the sun?...93,000,000 miles? \n" ); document.write( "

\n" );
