3. is the answer, as you can see D is one and a half units to the right of the y axis at a height of 3 units and C is one and a half units to the left of the y axis with the same height. So D is "reflected" about the y axis and only the x coordinate changes sign from positive to negative.
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)
