\n" ); document.write( "You have a special survey tool that lets you look up at objects at a 30 degree angle relative to the ground. You place the object on the ground in such a way that the nearby top of a tree appears in the viewfinder. If the distance from the tool to the bottom of the tree measures 14.7 feet. What is the height of the tree in feet?

You can put this solution on YOUR website!
You have a distance on the ground, 14.7 feet, and an acute angle at the ground of 30 degrees. You can use TANGENT of 30 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let y be the height of tree from ground to top.
\n" ); document.write( "\"y%2F14.7=tan%2830%29\"
\n" ); document.write( "You wanted to step using radians, so \"tan%28pi%2F6%29=%281%2F2%29%2F%28sqrt%283%29%2F2%29=1%2Fsqrt%283%29\", and you can use it in this form.
\n" ); document.write( "\"y=14.7%2Atan%28pi%2F6%29\"
\n" ); document.write( "\"y=%2814.7%29%281%2Fsqrt%283%29%29\"
\n" ); document.write( "Rationalize the denominator if you want...
\n" ); document.write( "\"highlight%28y=%2814.7%29%2Asqrt%283%29%2F3%29\"
