Answer:

The value of x is 12 units.

Step-by-step explanation:

Formula: h² = a² + b²

<u>Let's solve using Pythagoras theorem.</u>

=> 13² = 5² + x²
=> 169 = 25 + x²
=> 169 - 25 = x²
=> 144 = x²
=> √x² = √144
=> x = √144
=> x = 12

Hence, the value of x is 12 units.

In the diagram below, triangle abc ~ triangle dec . What is the value of x? A. 28 b. 24 c. 22 d. 26

Lesechka [4]

Answer:

Option A.

Step-by-step explanation:

From the figure attached,

Given : ΔABC ~ ΔDEC

By the property of similarity,

"Corresponding sides of the similar triangles are proportional"

$\frac{\text{AB}}{ED}=\frac{BC}{EC}=\frac{AC}{DC}$

Since, $\frac{\text{AB}}{ED}=\frac{AC}{DC}$

$\frac{42}{6}=\frac{x}{(32-x)}$

6x = 42(32 - x)

6x = 1344 - 42x

6x + 42x = 1344

48x = 1344

x = $\frac{1344}{48}$

x = 28 units

Therefore, Option (A). x = 28 units will be the answer.

I'd say A. 8000, because you'd get the most answers and the biggest variety in answers for a more accurate sample.
