PLEASE HELP!! ASAP!!

Corey spies a bald eagle in a tall tree. He estimates the height of the tree to be 70 feet and the angle of elevation to the bird from where he stands to be 42°. The sun coming up over the tree makes it difficult to see the bird, so he moves 40 feet closer to the tree to still see the bird.
What is his new angle of elevation to the bird? Round your answer to the nearest hundredth of a degree.
