Atree that is 35 feet tall cast a shadow that is 60 feet long. find the angle of elevation to the nearest degree

For questions like these you should draw the dimensions as a right triangle and use sine, cosine, and tangent to determine the answer. In this case, tangent is our friend.

The angle we need is equal to

which is the tree height divided by the shadow length. All we have to do is inverse the function and do
