You can put this solution on YOUR website! angles are measured from the positive horizontal axis, and the positive direction is counterclockwise. what are the values of sine B and cosine B in the 4rth quadrant?
In Quadrant IV:
sin<0
cos>0
Note: cos>0 in the right half of the unit circle and <0 in the left half
sin>0 in the top half of the unit circle and <0 in the bottom half
