Answer:
3695.5 m
1530.73 m
Step-by-step explanation:
Given in the question,
The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m
We will use trigonometry identities
<h3>sinФ = opposite / hypotenuse</h3><h3>cosФ = adjacent/ hypotenuse</h3>
1)
distance of probe from top of sea to surface = x
cos(90 - 67.5) = x / 4000
x = 3695.5 m
2)
horizontal distance from ship to probe = y
sin(90-67.5) = y / 4000
y = 1530.73 m

Step-by-step explanation:
5/6 of an hour is 60 minutes divided by 6 times 5:
60 / 6 * 5
10 * 5
50
Band practice was 50 minutes. 2/5 of band practice is 50 divided by 5 times 2:
50 / 5 * 2
10 * 2
20
