## kymber I don't understand how to do problems like these :'( one year ago one year ago

bears...or 42 im unsure which

3. kymber

BLEEEEEEEEH

4. jasonsmart

not helping?

5. experimentX

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

6. kymber

Can you explain, though!!?

7. experimentX

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

8. satellite73

trig ratios is what you need to know for these

9. satellite73

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

10. kymber

I know the trig ratios, SOH CAH TOA

11. satellite73

oh no, it is sine my fault!!

12. satellite73

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

13. kymber

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

15. satellite73

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

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

got that or still confusing?

18. kymber

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

19. satellite73

yw we can try another if you like

20. kymber

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