Question

Just an answer please!

One leg of a right triangle is 12, and the hypotenuse is 20.

The length of the other leg is___

Answer 1

@amistre64

Answer 2

C^2=a^2+b^2 . The pythagorean theorem.

You know C. You know a. Find b.

Answer 3

We are not here to provide answers. You will never learn by copying down the answers without understanding what you are doing.

Answer 4

Yep.

Answer 5

20^2 + 12^2 = Answer?

Answer 6

so 544 is the answer? @Dido525

Answer 7

No. In the Pythagorean theorem C is the hypotenuse and a, b are the legs of the triangle.

Answer 8

\[a^2 + b^2 = c^2\]
с is the hypotenuse. Make sure that you plug in the numbers properly

Answer 9

So its 23 ?

Answer 10

No. Show us your work.

Answer 11

Okay
20^2 + 12^2 = 544

Squared root of 544 is 23.32

Answer 12

Careful! You plugged in the numbers wrong.

Answer 13

What? How?

Answer 14

The Hypotenuse is the c value. You accidiently said the hypotenuse is a.

Answer 15

The formula is c^2=a^2+b^2 .

C is the hypotenuse.
a is the leg of a triangle
B is the other length

Answer 16

Leg sorry not length.

Answer 17

on my lesson it says a^2+b^2=c^2

Answer 18

Its the same thing written backwards :p .

Answer 19

I just chaged around where the terms are.

Answer 20

But it dosent matter. A^2+b^2=c^2

Answer 21

You know the c value which is the hypotenuse. You know the a value. You are trying to find b.

Answer 22

Do you understand?

Answer 23

then what the heck, you said C^2= blah blah right? So how did i plug it in wrong?

20^2 + 12^2 = 544

Answer 24

a=12, c=20, find b

Answer 25

12^2 + b^2 = 20^2

Answer 26

I didnt want to give it away :/ .

Answer 27

b^2 = 20^2 - 12^2
b^2 = (20+12)(20-12)
solve for b

Answer 28

$$ a = \sqrt{20^2 - 12^2} = \sqrt{400 - 144} = \sqrt{256}= 16 $$

Answer 29

THANK YOU! :D

Answer 30

Dont give her the answer



Sigh...

Answer 31

@mikelo40 it's better to solve problem yourself then to just copy answers from here or book, take your notes from the class, consult your teacher for problems with understanding, math is realy fun when you get it!

good luck :)

Answer 32

Thanks for that at least.
