sin is opposite over hyp

5. AonZ

now can you see what will sin theta be?

6. Cookieyumm

Question, though.. Why is the one angle and side 10?

7. AonZ

the angle is theta lol :) $\sqrt{8^{2} + 6^{2}}$ by pythag :)

8. Cookieyumm

Ohhh, okay. Yeah i'm not so good with this unit but that cleared it right up thank you (:

9. rizwan_uet

you want to find theta or sin theta????

10. Cookieyumm

sin theta, so the it would be sin(10) which would be 6/10, right?

11. AonZ

yes :)

12. AonZ

3/5 to be more simplier

thanks @AonZ

15. rizwan_uet

now its pretty much clear that sin theta = 6

16. AonZ

no problem :)

Understand why the hypotenuse is 10, but don't see the angle being 10 degrees.

18. radar

The hypotenuse could also be 20 and so on.
