1.     Corey spies a bald eagle in a tall tree. He estimates the height of the tree to be 80 feet and the angle of elevation to the bird from where he stands to be 68°. The leaves on the tree make it difficult for Corey to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.

How many feet did Corey step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.

See below......  solve for 'x'

198 is found by    tan 68 = 80/d       then  d = 198
