Question

Help.

Answer 1

use \[a^2+b^2=c^2\]

Answer 2

\[a^2+b^2=c^2\]

Answer 3

Pythagorean Theorem

Answer 4

To find the exact value, you have to find the radical.

Answer 5

I got b2=20..

Answer 6

What do I do now?

Answer 7

You have only found the difference. Now you need to find the radical of 20 to figure out \[b^2\]

Answer 8

That confuses me.. I thought it was a2+b2=c2... where did all this come from?

Answer 9

I don't know how to figure that out

Answer 10

As you can see that b is squared. Meaning that the original amount of b is multiplied two times. Now you need to actually find what two numbers were multiplied to get to b^2.

Answer 11

why are you putting in 6^2 where b should be when I don't have b?

Answer 12

OOPS

Answer 13

@calculusxy how do I figure that out?

Answer 14

I am wrong

Answer 15

I misread the question.

Answer 16

Well so far, you have had:
\[4^2+b^2=6^2\]
Am I correct?

Answer 17

Right

Answer 18

so that made 16+b2=36
So I isolated b2=20

Answer 19

What b2 means in this case is that a number was multiplied two time to approach to 20. So you need to find the radical of 20.
\[\sqrt{20}\]

Answer 20

so 4.47

Answer 21

See where this belongs to in which box.

Answer 22

Would my first answer just say square root 20 and the second by 4.47

Answer 23

Second I am pretty confident that it should be 4.47. But I am confused with the first question's wording.

Answer 24

Ok.. I will try that and hope it's right lol

Answer 25

Thank you!!

Answer 26

No problem :)

Answer 27

Can you tell me if it is correct or incorrect? I may also be learning something new.
