Answer:
<em>a) the angle of ascent is 8.2°</em>
<em>b) the horizontal distance traveled is 4375 m</em>
Step-by-step explanation:
depth of ocean = 626 m
distance traveled in the ascent = 4420 m
This is an angle of elevation problem with
opposite side to the angle = 626 m
hypotenuse side = 4420 m
a) angle of ascent ∅ is gotten from
sin ∅ = opp/hyp = 626/4420
sin ∅ = 0.142
∅ = 0.142
∅ = <em>8.2° this is the angle of ascent of the submarine.</em>
b) The horizontal distance traveled will be gotten from Pythagoras theorem
= +
The horizontal distance traveled will be the adjacent side of the right angle triangle formed by these distances
= +
adj =
adj = <em>4375 m this is the horizontal distance traveled.</em>
