HI!!

2. jjuden

$a. \frac{ \sqrt{3} }{ 3 } b. \frac{ \sqrt{3} }{ 2}c. \frac{ 1 }{ 2 }d.\sqrt{3}$

3. jjuden

hi

4. misty1212

you need a unit circle cheat sheet

5. misty1212

find 30 degrees on the unit circle then find the coordinates of that point the second coordinate is sine

6. jjuden

there are 2 options that will work

7. misty1212

no only one

8. misty1212

sine is the SECOND coordinate

9. jjuden

so 1/2

10. misty1212

yes

11. jjuden

ok thank you :)
