Katen [24]

Answer:

The height of the lighthouse is 742.5\ ft

Let

h -----> the height of the lighthouse

The tangent of angle of 68 degrees is equal to divide the height of the lighthouse by the horizontal distance from the buoy to the base of lighthouse

so

tan(68\°)=\frac{h}{300}

Solve for h

h=(300)tan(68\°)=742.5\ ft
