 The Washington Monument is 169 meters high.
 Find the angle of elevation to the nearest degree to the top of the monument from a point .5 km from the base
:
Change .5 km to 500 meters
:
Use the tangent of the angle (A), side opposite(169)/side adjacent(500)
tan(A) = {{{169/500}}}
A = 18.675 ~ 19 degrees
