The captain of a boat knows that a lighthouse on the coast is 100 ft
Tatiana [17]

Answer:

Height of the light house =7.5\ feet

Step-by-step explanation:

Distance of light house from boat = 100 ft

Angle of elevation from boat to the top of light house = 2°

Height above water while taking measurement = 4 ft

The figure of the situation is shown below.

For Δ ABC

\tan2\°=\frac {AB}{BC}

\tan2\°=\frac {AB}{100}

0.035=\frac {AB}{100}

Multiplying both sides by 100.

100\times 0.035=100\times\frac {AB}{100}

3.5=AB

∴ AB=3.5

Height of the light house =3.5+4=7.5\ feet
