Challenge! Ready? A tree that is 10 yards tall casts a shadow 14 yards long. Find the angle of elevation from the tip of the shadow to the top of the tree. Round to the nearest degree.

Question

wolf1728 · Answer

The shadow length would be the adjacent side and the tree would be the opposite side.
tangent (angle) = opp/adj
tangent (angle) = 10/14
tangent (angle) = 0.71429

Can you figure it out from here?

I already know the answer. It is 36 degrees

wolf1728 · Answer

okay the arc tangent of .71429 is
35.538 Degrees
Which rounds to 36 degrees
Did you want to know how it is done?
