Cape Beale Lighthouse, BC, is

on a cliff that is 51 m above sea

level. The lighthouse is there

to warn boats of the danger of

shallow waters and the

possibility of rocks close to the

shore. The safe distance for

boats from this cliff is 75 m. If

the lighthouse keeper is 10 m

above ground and observes a

boat at an angle of depression

of 50°, is the boat a safe

distance from the cliff? Justify

your conclusion.
