From a watch site on a ship the angle of depression to a raft is 10 degrees. The site is 94 feet above sea level. How far is the raft from the ship?

The raft is 16.57 feet far away from the ship.

Step-by-step explanation:

To find the distance of the raft from the ship if the angle of depression to a raft from a watch site on a ship is 10° and the site is 94 feet above sea level, we will follow the step below:

We can solve the problem using the trig. ratio

That is;

SOH CAH TOA

sin Ф = opposite / hypotenuse

cosФ= adjacent/hypotenuse

tanФ=opposite/adjacent

From the figure below;

angle Ф = 10°, we have adjacent= 94 feet   and opposite =x  where x is the distance of the raft from the ship.

so the best trig. ratio to use is tan

tanФ=opposite/adjacent

We can now proceed to insert the values into the formula

tan 10 =

multiply both-side of the equation by 94

94 × tan 10 =  ×  94

At the right-hand side of the equation, 94 will cancel-out 94 leaving us with just x

94 tan 10 = x

16.57 ≈ x

x≈16.57 feet

Therefore, the raft is 16.57 feet far away from the ship.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
