I put in the diagram

- youngnephew34

so you do 15+25

- youngnephew34

or would you do 15x2

- youngnephew34

so you doing 15x15

- anonymous

yes because 15x15 is the same thing as 15^2

- youngnephew34

so it will be 225=625

- anonymous

Hold on let me check everything first

- anonymous

Sorry man didnt see the 25 was the hypotenuse(C)
What I meant was 25^2-15^2=B^2

- anonymous

When you get B^2, you find the square root of that, You do the same thing there, but this time its B^2+9^2=X^2 The finally square root of X

- youngnephew34

9x9=81

- anonymous

yes

- youngnephew34

ok I got a different question

- anonymous

What is it

- youngnephew34

when you do 625-225=400 and you try 400x400160000

- youngnephew34

do you do 160000=81

- youngnephew34

I mean 160000+81

- anonymous

No after you get 400 you have to find the square root of 400

- youngnephew34

oh ok

- youngnephew34

it's 20

- youngnephew34

so you will do 40+81

- Directrix

Use the attached theorem to get:
x is to 25 as 9 is to 15
x / 25 = 9 / 15
Solve that for x.

121/25 gave me 4.84

- anonymous

But you really dont have to yet, because then you have to use 20^2*9^2=C^2

- Directrix

The triangle is not a right triangle. There is no hypotenuse or right angle. The Pythagorean Theorem does not apply here.

- anonymous

I thought so

- anonymous

I sort of doubted it

- youngnephew34

40x81 right or nah

- anonymous

dont think so

- Directrix

Solve this for x:
|dw:1447120695827:dw|

- youngnephew34

40x18=720

- anonymous

So .6?

- anonymous

Is dividing both separate legs(a) a rule?

- youngnephew34

I did 20x18 it gave me 720 and then I did 20+18 and that gave 38

- anonymous

No that is out of the question, we are using the theorem directrix gave us

- youngnephew34

but 6 isn't up there tho it 's 6

- Directrix

The answer is not 6.
|dw:1447121505057:dw|

- youngnephew34

is it suppose to be 5/25

- anonymous

what are the options really. is it 5/25 or 5 2/5?

- youngnephew34

5/25 =5 but what does 5 2/5 = to

- Directrix

|dw:1447121819795:dw|

- Directrix

>>5/25 =5 NO
5/25 = 1/5

- youngnephew34

it gave me 0.65

- youngnephew34

5/25=25 and 1/5=5

- Directrix

What is 75 divided by 5 ?

- anonymous

Its not division it is shown as a fraction.

- youngnephew34

75/5=15

- youngnephew34

so is it 15

- Directrix

Correct.

- anonymous

@Directrix Where did you get 9/15 and how did it become 3/5
