#1. Why is the angle of depression from a light house to a boat the same as the angle of
elevation from the boat to the light house?
The angle of depression from the lighthouse and the angle of elevation from the boat are
alternate interior angles formed by the line of site (the transversal) and the parallel
horizontal lines.
#2. What strategy is used to solve angle of elevation and depression problems?
#3. Comment on who might use trigonometric ratios to solve angle of depression and
elevation problems and how?

Pilots, control tower operators, fire foresters, and surveyors all might use trig ratios
to determine the height or distance of an object.
