## Krispyhaha 2 years ago What is the value of x? If necessary, round your answer to two decimal places. ( Picture attached below )

1. Krispyhaha

use the pythagorean theorem : x^2 = 24^2 - 12^2 solve for x

3. swin2013

Pythagorean Theorem: a^2 + b^2 = c^2 In this case, you have the hypotenuse and the height so you can fill in it as: 12^2 + b^2 = 24^2 *b is the same thing as x and you can just solve for the missing variable by squaring the numbers and moving 12^2 over to the right side by subtracting it. Voila! the answer!

@swin2013 So 24^2=576, 12^2=144, 576-144=432 but whats the square root?

5. swin2013

Do you have a calculator?

6. Krispyhaha

Yea

7. swin2013

if not, just type it in google. square root of 432. you know that it is between 20 and 21 "

8. swin2013

since 432 is between 400 and 441

9. Krispyhaha

I got 20.78 would that be right?

10. swin2013
