Answer 1

Answer 2

Know what the pythagoreom theory is?

Answer 3

a^2 + b^2 = c^2? That's what you'd do. A and B = the known sides.

Answer 4

If I remember correctly, that is. Maybe Jim can shed some light on the matter?

Answer 5

It could be B and C are the known sides and you solve for A.

Answer 6

Answer 7

\[height= \sqrt{113^{2}-15^{2}}\]

Answer 8

hint: see attached

Answer 9

what do i have to solve?

\[\Large {\color{red}{x}}^2+{\color{green}{y}}^2={\color{blue}{z}}^2\]

\[\Large {\color{red}{x}}^2+{\color{green}{15}}^2={\color{blue}{113}}^2\]

\[\Large x^2+225=12769\]

\[\Large x^2+225-225=12769-225\]

\[\Large x^2=12,544\]

\[\Large \sqrt{x^2}=\sqrt{12,544}\]

\[\Large x=112\]

Answer 11

Ah so I was wrong. It was B and C and you solve for A. Makes sense.

Answer 12

Excellent work as usual Jim.

Answer 13

Thanks

Answer 14

yes great work! next!

The length of the hypotenuse of a right triangle is 14 inches. If the length of one leg is 6 inches, what is the approximate length of the other leg?

11.5 inches
12.6 inches
15.2 inches
20.0 inches

Answer 15

Give this one a try

Answer 16

the steps will be the same as before, just with different numbers this time

Answer 17

i still don't get it

Answer 18

which step are you stuck on?

Answer 19

all :( especially the beginning..

Answer 20

i sort of get it more at the end..

Answer 21

do you see how I set x, y and z to be the side lengths?

Answer 22

x is unknown
y is 15
z is 113

Answer 23

but why the letters y and z?

Answer 24

just any 3 letters really. x,y,z makes the most sense for me

Answer 25

it could be a,b,c
or
p,q,r

or any 3 letters you want

Answer 26

oh ok...

Answer 27

the letters are just placeholders for a number

example: y is a placeholder for 15

Answer 28

ok yea i get that.. moving on..

Answer 29

do you understand what I mean when I write \(\Large x^2\) ?

Answer 30

no

Answer 31

it means `x squared`

squaring any number means you multiply that number by itself

examples

\(\Large 7^2\) = 7 squared = 7*7 = 49
\(\Large 9^2\) = 9 squared = 9*9 = 81
\(\Large 14^2\) = 14 squared = 14*14 = 196

Answer 32

oh yea i get that.. ok next..

Answer 33

As practice, tell me what \(\Large 16^2\) is equal to

Answer 34

256

Answer 35

good

Answer 36

so hopefully you can see how I turned \(\Large 15^2\) into \(\Large 225\) ?

Answer 37

yes...

Answer 38

and you're able to see how I turned \(\Large 113^2\) into \(\Large 12769\) ?

Answer 39

yes...

Answer 40

so you can see how I solved that last equation for x? you understand all the steps?

Answer 41

I'm pretty sure

Answer 42

ok you'll use those same steps (just with different numbers) on this next problem

Answer 43

\[\Large x^2+y^2 = z^2\]
\[\Large x^2+6^2 = 14^2\]
solve for x
