You can put this solution on YOUR website!
There you go, by trigonometric functions you can solve the height of the pole.
\n" ); document.write( "The distance of 85 ft from where you are standing to the height of the pole with an inclination of 30 degree is the hypotenuse.
\n" ); document.write( "Let x= height of flag pole.
\n" ); document.write( "by trigonometry, sin30 = x/hypotenuse
\n" ); document.write( "x=(sin30)(85)
\n" ); document.write( "x= 42.50 ft, height of flag pole. This is what you're looking for.
\n" ); document.write( "But you can also solve the distance from where you are standing to the pole.
\n" ); document.write( "By Pyth. theorem, let distance = d
\n" ); document.write( "(h)^2 = x^2 + d^2
\n" ); document.write( "85^2 = (42.50)^2 + d^2
\n" ); document.write( "d^2 = 7225-1806.25
\n" ); document.write( "d= sqrt 5418.75
\n" ); document.write( "d= 73.61 ft\r
