Answer 1

06-16-91") =(-20) (say) then x = o coso = -15 cos(-9,0) = 0.26 Y ensino =-15 sin (-910) ² 15 So, fx) = 10:26, 15) is a poin in I quadran, so A I quadrant is correct. H (2,3) = (4.0) (Gay); hemen = 3 is in varasam. x = 12cos (3) = -1.4 Y = √2 Sin (3) = 0.2 so fr) =(-1:4, 0:2) is a poins in II a nararam. راک II. is thne. 18 (ricis co .).
