Sarla made a drawing of a geometric figure for a fabric print. The figure was a quadrilateral with a pair of angles measuring 40° each. If the figure she drew is a concave polygon, which of these could be the measures of the other two angles? Answer 130°, 150° 160°, 140° 200°, 80° 220°, 110°

    Concave is when a shape/figure has an inworded point like a "Cave"

    btw, the total interior angle of a quadilateral is 360

    360-40-40. That leaves you the total angle left for the other angles.
