Question

A right triangle is formed by joining three

Answer 1

Answer:

D:  $x^{2}$ = 576 + $7^{2}$

Step-by-step explanation:

Well you want to find what x is so you need the square root

We already have the area for one of the squares (576) which can help us find what x is.

And the bottom small square is 7 and since it's a sqaure all the sides are congruent/ same. Which means u get $7^{2}$.

And you need to add them all up to get what x is

and is $x^{2}$ since both sides of that triangle will have the same lengths, and when u have both of those lengths its easier to find the area

Hope this helped!
