Four triangles are shown. One side of each triangle lies on a ray, and the triangles are not drawn to scale. Based on these tria
ngles, which statement about x is true? A) x = 160, because 180 − (130 + 30) = 20 and 180 − 20 = 160 B) x = 20, because 130 + 30 = 160 and 180 − 160 = 20 C) x = 80, because 180 − 130 = 50 and 50 + 30 = 80 D) x = 340, because 130 + 30 = 160 and 160 + 180 = 340
