Question

As shown in the figure below, Mary is standing 31 feet from the base of a leaning tree. The length of the tree is 57 feet. The angle of elevation from where Mary is standing to the top of the tree is 73 degrees. Find the angle, theta, that the tree is leaning. Round your answer to the nearest tenth of a degree.

Answer 1

I think the answer is 150.

Explanation:

Because I added 73+57+31 and it equaled to 161.

Then I rounded to the nearest tenth of a degree and I got 150.
