Given: ABCD is a quadrilateral, BC║AD, m∠ A = 90°
Lina20 [59]

Answer:

  Rearrange the equations that result from use of the Pythagorean theorem.

Step-by-step explanation:

Transversal AB crossing parallel lines AD and BC makes supplementary interior same-side angles A and B. Since A = 90°, B must be 90°. The Pythagorean theorem then applies in the right triangles ABC and ABD.

We can use that theorem to write two expressions for AB^2:

  BD^2 -AD^2 = AB^2 = AC^2 -BC^2

The middle expression, AB^2, isn't needed beyond this point. Adding (AD^2 -AC^2) to both sides of the equation gives the desired result:

  BD^2 -AC^2 = AD^2 -BC^2

Yuri [45]

According to the calculation, each visitor went down, on average, 11.41 times.

<h3><u>Averages</u></h3>

Given that a water park keeps track of the number of times each visitor goes down water slides during their visit, and 12 visitors went down a water slide 4, 22, 16, 10, 11, 20, 20, 12, 6, 3, 11 and 1 times, to determine the average number of times each visitor went down, the following calculation must be performed:

  • (4 + 22 + 16 + 10 + 11 + 20 + 20 + 12 + 6 + 3 + 11 + 1) / 12 = X
  • 137 / 12 = X
  • 11.41 = X

Therefore, each visitor went down, on average, 11.41 times.
