28
45
53
98

Answer 1

Do you have an image? c:

Answer 2

yes going to post it now.

Answer 3

Do you know the pythagorean theorem?

Answer 4

The answer is 28

Answer 5

I forgot it. I use to be really good at it.

Answer 6

You do 53^2=45^2+x^2 solve for x then

Answer 7

Alright, so here's how it goes
a^2 + b^2 = c^2
Where c is the hypotneuse and a & b are the sides
Note: this can only be used in right triangles

So, a^2 is 45^2
we do not have b ^2, it is what we're solving for
we have c^2, which is 53^2

So we do this:
53^2 - 45^2 = b^2\

Can you solve that?

Answer 8

the answer would be 28.

Answer 9

Yep, great job c:
