yes I am aware that y= sin(theta) and x= cos(theta) and yes I drew my unit circle so sin20 is in the first quadrant but I am not sure how to import images here, if possible and cos70= sin 20, I figured that out a few days ago, however I am stuck on 3 and 4

Without a calculator, find all solutions w between 0 and 360, inclusive, providing diagrams that support your results. 1) cosW=sin20 2) sinW=cos(-10) 3) sinW< 0.5 4) 1<tanW
