I’m doing a review for a test and have the question: A forester, 200 feet from the base of a redwood tree, observes that the angle of elevation to the top of the tree is 57 degrees. Estimate the height of the tree.

My answer came out to be the tan(57) = opposite side/200 which comes out to be 200tan(57) = 307.97 ft.

Seems correct but would like to have my work double checked.
Thanks everyone for checking that. It really is appreciated.

Math is not my strongest subject. =P
