A quadrilateral has one elongated pointed end. The top interior angle at the upper vertex, measures $80^\circ$80° and is shaded purple. The left interior angle, measures $\left(x\right)$(x) and is shaded red. The largest interior angle, opposite the top interior angle, measures $155^\circ$155° and is shaded green. The bottom-right interior angle at the pointed end, measures $30^\circ$30° and is shaded light blue.
