Question

From the 100-foot roof of bobs condominium on the coast, he sights a cruise ship carrying Jimmy

the Giant Squid. The angle of depression is 2.5 deg How far is the ship from the shore line?

Answer 1

100/x = tan2.5

x =100/tan2.5 = 2,273 feet from the shoreline.

100 and the distance to the shoreline form two sides of a right triangle, with an angle 2.5 degrees

100 divided by the distance to the shoreline = tan2.5 = 0.044

100/.044 = about 2273
