<h3>Answer:   A) 20</h3>

========================================================

Explanation:

Use the chord intersecting theorem

The pieces of each chord multiply to the same products

(x-5)*(x-8) = x*(x-11)

x^2-13x+40 = x^2-11x

-13x+40 = -11x ...... x^2 terms cancel

40 = -11x+13x ..... add 13x to both sides

40 = 2x

2x = 40

x = 40/2   ..... divide both sides by 2

x = 20

A submersible traveling at a depth of 250 feet dives at an angle of 15 degrees with respect to a
kipiarov [429]

Answer:

\boxed{\text{652 ft}}

Step-by-step explanation:

The submersible is diving at a down angle of 15° along the hypotenuse AC of triangle ABC.  

Its horizontal track along the surface AB is 1500 ft.

\begin{array}{rcl}\tan A & = &\dfrac{BC}{AC}\\\\\tan 15^{\circ} & = & \dfrac{a}{1500}\\\\0.2679 & = & \dfrac{a}{1500}\\\\a & = & 1500 \times 0.2679\\& = & \textbf{402 ft}\\\end{array}

The submersible was already at a depth of 250 feet when it began the dive.

New depth = 250 + 402 = 652 ft

\text{The depth after the dive is }\boxed{\textbf{652 ft}}
