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?

160°, 140°

220°, 110°

130°, 150°

200°, 80°

how could it be????

anonymous · Answer

i think it should be 130, 150.
