Answer:
c. sin 30 is positive and sin -30 is negative
Step-by-step explanation:
Picture the unit circle (which is attached). <u>Sine is like the y-coordinate.</u> And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a <u>negative y-coordinate.</u> 30 is above the x-axis, so it has a <u>positive y-coordinate.</u>
