Answer 1

@sleepyjess

Answer 2

Do you know the Pythagorean Theorem?

Answer 3

Yes

Answer 4

Ok, we are going to use that here

Answer 5

ok

Answer 6

So what should i start by doing because they only give U side A which is 8

Answer 7

But since this is a 45-45-90 triangle, sides A and B are the same length :)

Answer 8

yes, use the fact that you know a=b, then plug into a^2+b^2=h^2

Answer 9

8^2+8^2=128

Answer 10

64+64=128?

Answer 11

that's h^2, but you need h

Answer 12

h^2=128 so what's h?

Answer 13

what should i do to find it?

Answer 14

I'll give you an example. If c^2 = 25, we would need to take the square root of both sides because \(\sqrt{c^2}\) is the same as c.

Answer 15

you have to take the square root

Answer 16

I was going to do the square root but i saw that there was no square root for it

Answer 17

well 128=8(16) right?

Answer 18

\[\sqrt{128}=\sqrt{(16)(8)}=\sqrt{16}\times \sqrt{8}\]

Answer 19

I knew this but i was thinking it had to be a number times itself. for example 11 x 11 or 12 x 12

Answer 20

not exactly those numbers i just gave u that as an example

Answer 21

that's how you simplify though. so do that until you can't anymore I guess lol

Answer 22

So 8sqrt2 is the answer?? @sleepyjess @Thefaceless

Answer 23

yes it is!
