Answer 2

Have you heard about the Pythagorean Theorem?

Answer 3

yes hah

Answer 4

i got 85.8 when using the pythagorean theorem ( i did 56 and 65)

Answer 5

??? like what do i do now??

Answer 6

@Kainui

Answer 7

How did you do 56 and 65?

Answer 8

i plugged it into the pythagorean theorem b/c it forms 2 sides of a triangle? right?

Answer 10

Answer 11

\[A^2 + B^2 = C^2\] Since you know you have one of the sides and the hypotenuse then you will have to solve for the other side

Answer 12

But you need to pay attention to what sides are what before you do it

Answer 13

Lets say A is the side you are solving for then you will see that you will need to manipulate your formula to solve for that side you are looking for:
\[A = \sqrt{C^2 - B^2}\]

You may may have ran into an error because of the side you used in the formula.

Answer 14

ahhhh can someone give me an example using different numbers?

Answer 15

Since C corresponds to the hypotenuse you know you have to treat it as C in the Pythagorean Theorem:
\[A^2 + B^2 = C^2\]

Answer 16

ohhh okay :)

Answer 17

If you like to work it out purely with numbers then you can begin with the formula and carry out the algebra for the missing variable, so for the example above:

\[A^2 + B^2 = C^2\]
\[(1)^2 + B^2 = (3)^2\]\[1 + B^2 = 9\]\[B^2 = 9 -1\]\[B^2 = 8\]\[B = \sqrt{8}\]

Answer 18

okay! thats easier to me !
