# Law of Sines: Bird watching

Corey spies a bald eagle in a tall tree. He was able to measure the angle of elevation to the bird from where he stands at 62°. The leaves on the tree make it difficult for Corey to watch the bird, so he moves 10 feet further away from the tree to get a better view. Now his angle of elevation is 56°. What is the height of the tree? Round your answer to the nearest foot. Trying to check my answer, I used law of sines to solve and want to know if I get it or not.

A sloppy question.

To begin with we need to know whether the 10ft away from the tree was on level ground or up or down a slope.

Further we are not told where the bird was in the tree, at the top or further down in the branches, or are we supposed to assume ?

Tighten up on the details and we may be able to do something.

Yes it is a sloppy question but you are basically expected to assume that it is the height of the bird that you are finding and that the ground is all level.

The answer I got was 39 feet.   Do you want me to explain further or did you just want to check your answer.?
