Answer 2

Answer:

Option B, $3.27$

Step-by-step explanation:

Given -

The submerged vessel travel horizontal distance above the shipwrecked hull

$= 400$

$= 0.4$ kilometers

The vertical distance from the the shipwrecked hull to the ground is equal to $7$ kilometers

There forms a right angled triangle with

Base $= 7$ kilometer

Perpendicular $=$ 0.4 kilometer

Tan (angle) $= \frac{Perpendicular}{Base}$

Substituting the given values we get -

Angle of depression

$= tan^{-1}(\frac{0.4}{7})\\= 3.27$

Hence, option B is correct.
