Two boats are drawn on a 14 by 15 grid. A small boat on the left is labeled A, and a bigger boat to the right is labeled B. A diagonal dashed line extends downward from boat A, and intersects with a vertical downward line from boat B, creating two triangles.

Given that AB¯¯¯¯¯¯¯¯ =9 units in length and BC¯¯¯¯¯¯¯¯=12 units in length, how many units is CE¯¯¯¯¯¯¯¯ ?

To solve for \( CE \), we can make use of the information provided about the lengths \( AB \) and \( BC \).

Given:

  • \( AB = 9 \) units (the distance between the two boats)
  • \( BC = 12 \) units (the vertical distance from point B down to point C)

From point A to point B, a diagonal dashed line extends downward, and from Boat B, a vertical line extends downward to point C.

Since triangles are formed and we are not given the specific angles, we can deduce from the information along the lines of height of a triangle. Here, the height of the triangle formed at point A to point C could logically imply a right triangle formation because of the vertical and horizontal lines stated.

To find \( CE \), we will use the following relationship from the properties of triangles:

Since the triangle \( ABC \) consists of:

  • The base \( AB \)
  • The height \( BC \)

Then the segment from \( A \) downward to point E on the same vertical line extending from B should logically form a right triangle to \( CE \).

  1. Since \( BC = 12 \) and forms a right triangle with \( AB = 9 \) where the heights add up from point A down, we should expect:

Using the Pythagorean theorem, \[ CE = BC - AB \] The length \( CE \) is directly calculated as: \[ CE = 12 - 9 = 3 \]

However, upon checking the conceptual understandings of vertical extensions and calculation:

The positioning indicates: \[ CE = BC - AB,( as length A extends down to intersect and form B) then CE = 12 + a additionals from vertical positions. \] Since \( AB \) and understanding states that the horizontal reach across along 14 units downwards lead proportionally across.

Retaking, resultants from equidistant stretchings indicates \( CE=24\) through vertical accumulations.

Thus the length of \( CE \) is calculated to be:

24 units.
