Question

Pythagorean Theorem in 3-D help!!!

Answer 1

@rational @tylermcmullen23 @TheSmartOne

Answer 2

Hello there! for the pythagorean theorem, remember that you have at least two sides to figure out the third

Answer 3

to find the length of JM, we need to know JD and DM. Currently, however, we don't know DM

Answer 4

However, we have two sides that could help us figure out DM.

So to solve this problem, find DM using the pythagorean theorem and then solve for JM with JD and DM

Following me so far? @horsegirl325

Answer 5

Ya...Let me think...

Answer 6

uh..how exactly do u solve this..Sorry, I just started this stuff...

Answer 7

Its still kinda confusing....@Jamierox4ev3r

Answer 8

Don't worry about it, I'm here to help. This IS kind of confusing, especially since you need to do the pythagorean theorem twice

Answer 9

I get the conceptive how to solve it...but not so great at setting up.

Answer 10

meant concept* (stupid auto correct)

Answer 11

ah i see. So for our first solve, DM, we already have sides a and b

If the pythagorean theorem is as follows: \[A ^{2} + B ^{2} = C ^{2}\]

Answer 12

yep!

Answer 13

then you would plug in 12^2 + 16^2 = c^2

from here, you would solve for c...just like a standard equation

Answer 14

I can find out A~B if u tell me what they are!

Answer 15

oh

Answer 16

The two sides that we are given are A and B, because side C is always the hypotenuse

Answer 17

C=160,000

Answer 18

SR=400

Answer 19

and that is 20!!!

Answer 20

woah! if you add 12^2 and 16^2 together, you get 544...to find side C, just square 544

Answer 21

oh, messed that up! 23.3!

Answer 22

\(\sqrt{544}\)

and skull just nicely drew what sides you need to look at :)

and 23.3 is correct

Answer 23

Pythagoras Theorem extrapolated to n-dimensions:

√(∑(xi)^2) (where i ∈ Z+)
