An angle is drawn on the unit circle such that its terminal ray is in the second quadrant. If sin 0 = 0.809, then what must be true about sin(-o)?

sin(-6) 0.809
sin(-0) = -0.588
sin(-0) 0.588
sin(-0) = -0.809

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

a. positive: 2 or 0; negative : 2 or 0; complex: 4or2or0
