## Ammarah 2 years ago Classify the triangle formed by the side lengths as right, acute, or obtuse.

If a^2 + b^2 = c^2 Then the triangle is right If a^2+b^2 > c^2 Then the triangle is obtuse If a^2 + b^2 < c^2 Then the triangle is acute

thats not right

5. NotTim

y not?

6. Ammarah

it is?

7. Ammarah

so how would u solve it?

8. Ammarah

It would be a right triangle right?

9. NotTim

why not use Cosine Law to figure this out?

10. Ammarah

use ?????????? we use a the pythagreoam theorem.......i dont now what ur talking about

11. NotTim

Well if Cosine Law can't be used, I think eyust707 provided enough information

12. Ammarah

?????what the hell r u talking about??

13. Ammarah

shut up and leave

14. Ammarah

15. Ammarah

/im really desperate..........

16. NotTim

really?

17. NotTim

eyust707 gave you everything you need, if you don't want to use Cosine Law.

18. NotTim

Alongside Sine Law and all that.

19. Ammarah

oh ohk

20. Ammarah

could u guys check the whole wkst for me please?

Follow what eyust707 wrote. If the triangle is a right triangle, then if you use those three side lengths in the Pythagoras Theorem formula, it'll make it true. This is how you test it: |dw:1357793926961:dw|

22. Ammarah

Yess I got that thankyou!

23. Ammarah

could u look at the other problems for me?
