Which of the following could be the side lengths of a right triangle

ASHA 777 [7]

The lengths of a right triangle's three sides can be expressed as 24, 32, and 40.

Let's work our way through the solution. According to the right triangle formula, a triangle's hypotenuse square equals the sum of its base square and its altitude square.

How to determine a right triangle's sides?

If leg an is absent, change the equation to its form when leg an is present on one side and compute the square root: a = (c2 - b2).

Leg b must be unknown otherwise. b = √(c² - a²)

The equation for hypotenuse c is: c = (a2 + b2)

What is the location of the point (5, 0) translates 4 units to the down and reflected across the y-axis?

CaHeK987 [17]

STEP-BY-STEP EXPLANATION:

Given information

The given ordered point = (5, 0)

Step 1: We need to translate the point 4 units down

To translate down means we will be subtracting a value from the y--axis

Hence, we have

$\begin{gathered} (x,\text{ y) }\rightarrow\text{ (x, y-b)} \\ \text{where b = 4} \\ (5,\text{ 0) }\rightarrow\text{ (5, 0 - 4)} \\ (5,\text{ 0) }\rightarrow\text{ (5, -4)} \end{gathered}$

When translated 4 units down, we got (5, -4)

Step 2: Reflect over the y-axis

The general rule for reflecting over the y-axis is (-x, y)

This means the value of x will be negated and the value of y will remain the same
