A man is standing near the Washington Monument. At a 60° angle of elevation from the ground, the man sees the top of the 555-foot monument.
A man is standing near the Washington Monument to form a triangle. The height of the monument is 555 feet. The angle where the man is standing is 60 degrees. The monument and the ground form a right angle.
Which measurements are accurate based on the scenario?

I have tried solving the problem, and none of the values in the choices matched with mine.

Illustrating the problem, it shows a right triangle, one angle is 60° with the opposite vertical side measuring 555 ft which is the height of the monument. Using the pythagorean theorem, the distance between the man's feet to the top of the monument being the hypotenuse (longest side), the hypotenuse would be 640.86 ft and the distance from the man's feet to the monument's base is 320.43 ft.

sin 60 = 555/hypotenuse

hypotenuse = 640.86 ft

tan 60 = 555/base

base = 320.43 ft
