Use Green's Theorem to evaluate the following integral, (erz +20y) dx + (1014 - 20x) dy where C is the curve that starts at the origin, and then goes along a straight line to the point (7, 7), and then along the arc of the circle x+12 line back to the origin. = 14 from the point (7, 7) to the point (0, 14), and then along a straight V
