## Desireegb 3 years ago Help? I don't know what I'm doing wrong... Use the table for sine values, and find x to the nearest tenth. (My Answer) x (Approximately) = ? 1.0

1. Desireegb

2. aroub

sin(48)=10/x

3. aroub

Is this what you did?

4. Desireegb

oh wait, i think i may know now, heres my work sin 48* = x/10 sin 48* = 0.7431 0.7431 = x/10 x = 10(0.7431) 0.1

5. aroub

No, what is sin?

6. lawrenceh123

sin is opposite over hypotenuse and could one of you help me with my question please

7. Desireegb

i could try sry i was away from the computor when u asked what sin was

8. Desireegb

i hav instructions for the lesson and the definition they gave me for Sine ratio was: with respect to an acute angle of a right triangle, the ratio formed by the side opposite the acute angle over the hypotenuse.

9. Desireegb

i looked over ur problem and i dont really understand what to do on that either sorry :(

10. aroub

Okay, sin is opposite over hypotenuse. Sin 48= opposite/ hypotenuse. What's the opposite of sin 48?

11. Desireegb

10 right?

12. aroub

Yup!

13. aroub

14. Desireegb

so that would be sin 48* = 10/x

15. aroub

Exactly :)

16. Desireegb

okay so the problem would be: sin 48* = 10/x sin 48* = 0.7431 0.7431 = 10/x 10 = x(0.7431) and then i divide?

17. aroub

Yes

18. Desireegb

k i got 0.07431 so that goes to 0.1 when rounded right?

19. aroub

How did you get that? O.o!

20. Desireegb

i divided 0.07431 by 10 and i got 0.07431 and i rounded to the nearest tenth and since 7 is a high number i rounded it to 0.1

21. aroub

yepp :D

22. Desireegb

awesome lol
