Question

U-Boat

Answer 1

Answer:

$x=24.44^{\circ}$

Explanation:

Given that,

German U-boats would dive 150 meters below the surface. If an enemy ship was 330 meters away on the surface.

We need to find at  what angle of elevation x should the U-boat shoot to hit the ship.

150 m is the height, 330 m is the base of the right angle triangle. We can find the angle of elevation as follows :

$\tan\theta=\dfrac{P}{B}\\\\\tan x=\dfrac{150}{330}\\\\x=24.44^{\circ}$

So, the angle of elevation is $24.44^{\circ}$.
