A transversal cuts parallel lines. Going around one intersection point, the four angles in order are $y$ , 70°, $y$ , 70 deg (alternating equal).
What is the value of $y$ (deg)?

Question

A transversal cuts parallel lines. Going around one intersection point, the four angles in order are y, 70°, y, 70 deg (alternating equal). What is the value of y (deg)?

Accepted Answer

110. Adjacent angles around a point on a line form linear pairs: y + 70 = 180, so y = 110°.
