These two triangles are similar and the conversion factor is 2/3. This can be found by dividing one side length corresponding to the other on the other triangle.

In this case, DF ~ AC

DF = 12

AC = 18

12/18 = 2/3

Knowing this, we can multiply 15 by 2/3 to find the length of DE because side lengths AB and DE are similar.

15 • 2/3 = 10

DE = 10

Point Z is at a horizontal distance of 15 meters from the left- most point of the dam . What is the height of the dam at point Z

Ivanshal [37]

Complete Question:

The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.

Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?

Answer:

The height is 36 meters

Step-by-step explanation:

Given

$y = 24 * \frac{x}{10}$
