**drwls**, Wednesday, October 5, 2011 at 8:51pmThe tree height is 25 tan32 = 15.6 feet

To the nearest foot, that would be 16.

I assume you are familiar with the tangent of an angle.

25ft

The 32 degrees should go in the bottom left corner of the triangle. To solve for x, you would use tangent. The problem would be set up as tan(32)=x/25

Then, mulitply both sides by 25 to get x by itself so you have:

25tan(32)=x

When you plug this into a calculator, you get 16.525, so the tree is about 17ft tall
