Answer:
The 13.2 meters from that point on the ocean floor to the wreck.
Explanation:
As given
A ship's sonar finds that the angle of
depression to a ship wrack on the bottom of the ocean is 12.5°.
If a point on the ocean floor is 60
meters.
Now by using the trigonometric identity.
tano = Perpendicular /Base
As shown in the figure given below.
Perpendicular CB
Base AC = 60 meters
0 = 12.5°
Put in the identity CB
tan 12.5°
AC
tan 12.5° CB 60
tan 12.5° 0.22
tan 12.5° = 0.22
0.22 CB 60
CB = 60 × 0.22
CB= 13.2 meters
Therefore the 13.2 meters from that point on the ocean floor to the wreck.
