bears...or 42 im unsure which

3. kymber Group Title

BLEEEEEEEEH

4. jasonsmart Group Title

not helping?

5. experimentX Group Title

$\sin 50 = 100/x$ find x using calculator

6. kymber Group Title

Can you explain, though!!?

7. experimentX Group Title

$\sin \theta = p/h$ the question is asking you to find h ... and also note this is a right angled triangle

8. satellite73 Group Title

trig ratios is what you need to know for these

9. satellite73 Group Title

btw it is not sine in this case but tangent i think

10. kymber Group Title

I know the trig ratios, SOH CAH TOA

11. satellite73 Group Title

oh no, it is sine my fault!!

12. satellite73 Group Title

should have known better. do you know the trig ratios for a triangle?

13. kymber Group Title

Is it not SOH CAH TOA?!?!!?!

15. satellite73 Group Title

so for the angle given , lets call it $$x$$ in terms of $$a, b, c$$ can you say what $\sin(x)$ is? you are right, you can use soh cah toa if you know what they mean

16. satellite73 Group Title

so in your picture, you are trying to find the hypotenuse $$h$$ so you know from "SOH" that the sine of 50 is the opposite over the hypotenuse, or $\sin(50)=\frac{100}{h}$ and then you solve for $$h$$ via $h=\frac{100}{\sin(50)}$

17. satellite73 Group Title

got that or still confusing?

18. kymber Group Title

Uuh, I think I got itt, thanks a bunch for helping meee! :D

19. satellite73 Group Title

yw we can try another if you like

20. kymber Group Title

That's okaay, I'm prettyy sure I got it! c;
