Answer 2

@dan815

Answer 3

you can use Pythagorean or the distance formula

Answer 4

lets use pythagorean

Answer 5

label the side lengths that we know from the picture

Answer 6

leg a and b are both 3

Answer 7

I seriously don't get it but no one wants to help me with this dang question so i guess ill get it wrong

Answer 8

I was helping someone else for a second. Anyways, 3 is correct for both sides

Answer 9

are you familiar with the pythagorean theorem?

Answer 10

c≈4.24

Answer 11

and yes

Answer 12

That's right, and what is that also written as?

Answer 13

I dont know

Answer 14

how did you get 4.24?

Answer 15

c=a2+b2

Answer 16

the google calculator for the therom or whatever it is

Answer 17

Doing the algebra will give you the answer

Answer 18

so we get 3^2 + 3^2 = c^2

Answer 19

can you solve for c in this?

Answer 20

I just need to answer im running out of time to study for my test

Answer 21

it's pretty easy man. What is 3^2?

Answer 22

I dont know what that is

Answer 23

9?

Answer 24

3^2 is the same as 3 x 3

Answer 25

that's right, its 9

Answer 26

so we have 9 + 9 = c^2

Answer 27

9 + 9 =18 so we are left with 18 = c^2

Answer 28

9+9= 18 and then 18 - 4.24 x 4.24 is ...

Answer 29

nope.
we have 18 = c^2

Answer 30

The opposite of ^2 is ^1/2 also known as the square root

Answer 31

4.24 x 4.24 is about 18

Answer 32

so we are left with c = sqrt(18)

Answer 33

Which is the answer
