uhhh thats not enough to do anything with

3. SolomonZelman

yes, please give us some equation to work on:)

@KakeFace @DaBest21 @SolomonZelman

7. SolomonZelman

$$\large\color{black}{ \displaystyle \frac{ x }{{\rm Sin}(90)} =\frac{19}{{\rm Sin}(20)} }$$

8. SolomonZelman

sines law:)

9. anonymous

idk sry

10. emmaleelooney

thanks anyways @KakeFace and @SolomonZelman I'm gonna try and put that together but im not sure that I'm going to get it right...

11. SolomonZelman

you just have to use the calculator also, know that sin(90º)=1

12. SolomonZelman

so all you have is  x = 19 / Sin(20)

13. SolomonZelman

while you are calculating I will post some general info about the sines law.

14. emmaleelooney

okay... and I got 55.5

15. emmaleelooney

?

16. emmaleelooney

so i would round it to 55.6

17. SolomonZelman

|dw:1435592329614:dw|} yes correct

18. SolomonZelman

And as relates to that picture I will post the formula

19. SolomonZelman

$$\LARGE{\bbox[5pt, lightcyan ,border:2px solid blue ]{ \displaystyle \frac{ {\rm Sin(A)} }{a}=\frac{ {\rm Sin(B)} }{b}=\frac{ {\rm Sin(C)} }{c} }}$$

20. emmaleelooney

Okay, so just to clarify ... 55.6 is the right answer?

21. SolomonZelman

or, same way can you say that: $$\LARGE{\bbox[5pt, lightgreen ,border:2px solid green ]{ \displaystyle \frac{a}{ {\rm Sin(A)} }=\frac{b}{ {\rm Sin(B)} }=\frac{c} { {\rm Sin(C)} } }}$$
