Consider a polygon on the screen with vertices $(30,0),(0,20),(20,50)$ and $(40,30).$ Assuming we are using Gouraud shading, and that each of the points have the following RGB values$(0\mathrm{.}9,0\mathrm{.}6,0\mathrm{.}1),(0\mathrm{.}7,0\mathrm{.}8,0\mathrm{.}1),(0\mathrm{.}0,0\mathrm{.}4,0\mathrm{.}5),(0\mathrm{.}2,0\mathrm{.}1,0\mathrm{.}8),$ respectively $$ determine the RGB values for points $(30,30)$ and $(20,10).$ Be sure to show your work.
