The length of the hypotenuse of a right triangle is 24 inches. If the length of one leg is 8 inches, what is the approximate length of the other leg? 16.0 inches 18.4 inches 22.6 inches 25.3 inches

2. anonymous

use the Pythagorean Theorem

3. anonymous

a squared+ b squared= c squared

4. anonymous

so do 24 squared - 8 squared

5. anonymous

then find the square root of 512

6. anonymous

ok thts 16

7. Astrophysics

|dw:1438606497888:dw| use pythagorean theorem as mentioned by @heretohelpalways

8. Astrophysics

No...it's not 16, try again.

9. anonymous

no

10. anonymous

24-8=16

11. Astrophysics

$x^2+y^2=r^2$ |dw:1438606601072:dw|

12. anonymous

576-64

13. anonymous

then find the square root of that answer

14. anonymous

no, it is 24 squared - 8 squared

15. anonymous

512

16. anonymous

correct, now find the square root of 512

17. anonymous

how do i do tht

18. Astrophysics

$r^2 = x^2+y^2 \implies x = \sqrt{r^2-y^2} = \sqrt{(24)^2-(8)^2}$

19. anonymous

umm 448

20. Astrophysics

??

21. anonymous

sorry i did 512-64 and i got 448

22. anonymous

no 576-64

23. Astrophysics

Oh no, look at the equation above, just follow that

24. anonymous

idk how to find the root for 512

25. Astrophysics

Use a calculator

26. anonymous

$x ^{2}=512$

27. anonymous

k brb

28. anonymous

thx

29. anonymous

ok help me with another?

30. anonymous

just remember that $a ^{2}+b ^{2}=c ^{2}$

31. anonymous

ok

32. anonymous

okay, can you start a new post?

33. anonymous

k
