Pythagoras!!!

12. Romero

$x^2 + y^2 = z^2$

13. math456

but we dont know the values..

14. Romero

Only for the second one lol sorry.

15. Romero

$x^2 + 7^2 = a^2$

16. Romero

solve for x

17. math456

sq. root a-7

18. Romero

$\pm \sqrt{a^2 - 7^2}$sq. root a^2-7^2

19. Romero

For the other ones you have to use cos sin and tan

20. math456

ohh okay, so this is all we have to do?

21. Romero

I did b

22. math456

23. math456

like for a) is it x=+/- sq. root a-43 degress

24. Romero

That's what I mean. You have to use cos sin tan SIN COS TAN SOH CAH TOA O=opposite side A=adjacent side H=Hypotnus

25. Romero

Go learn how to use cos sin and tan.

26. brattygirl0962

what do u neeed help with the same thing

27. math456

i know abt them already.. but not sure how to use it here..

28. Romero

If you know it already then you would know how to use them exactly. Even with my information that I have you about cos sin and tan GO back to that section and review it.

29. math456

is it like sin(43)=x/a-->a sin(43)=x?

30. math456

thanks for part b!!

31. Romero

Cos(43)=a/x Adjacent side is a over hypotnus which is x CAH

32. Romero

c) use tan d) use sin

33. math456

thank you..
