Four triangles are shown. One side of each triangle lies on a ray, and the triangles are not drawn to scale.

Based on these triangles, which statement about x is true?

• x = 160, because 180 -  (130 + 30) = 20 and 180 - 20 = 160

• x = 20, because 130 + 30 = 160 and 180 - 160 = 20

• x = 80, because 180 - 130 = 50 and 50 + 30 = 80

• x = 340, because 130 + 30 = 160 and 160 + 180 = 340
