sin is opposite over hyp

5. AonZ Group Title

now can you see what will sin theta be?

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

7. AonZ Group Title

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

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

9. rizwan_uet Group Title

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

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

11. AonZ Group Title

yes :)

12. AonZ Group Title

3/5 to be more simplier

thanks @AonZ

15. rizwan_uet Group Title

now its pretty much clear that sin theta = 6

16. AonZ Group Title

no problem :)

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

The hypotenuse could also be 20 and so on.
