Question

As observed from the top of a 150 m tall light house, the angles of depression of two ships approaching it are 30° and 45°. If one ship is directly behind the other, find the distance between the two ships.

Answer 1

Answer:

Step-by-step explanation:

Tan0=opposite/adjacent

Tan30°=150/x

Tan45°=150/y

1/2=150/x

X=300m

Now

1/√2=150/y

Y=150×√2

Y=212m

Distance between the two ships =300-212

=88m
