Question

You are standing on an elevated observation platform 220 feet away from a tree on which you spot a monkey. You measure the angle of depression to the bottom of this tree to be 19∘, while the angle of elevation to the top of the tree is 31∘. The angle of elevation to the monkey is 29∘.

The height of the observation platform is:  feet.

The height of the tree is:  feet.

The height of the monkey above the ground is:  feet.

(You may give your answers as decimal approximations.)

Answer 1

Draw a figure!!!

The height of the tower is the easy one...I won't do it for you.

The height of the top of the tree above the observer is 220* tan 31°.

You should now know what the height of the tree is.

And the answer to the monkey's height above ground should be easy now too.
