Question #10560

Given two parallel lines with a transversal, if one of the angles measure 50 degrees, find the measures of all other angles. Explain how you found the angles.

Expert's answer

______________________________________

& & & & & & & & & & & & & & 50 / 180-50 = 130

& & & & & & & & & & & & & & /

& & & & & & & & & & & & & & /&

& & & 180-50 = 130 & /& 50

______________ _/______________________

Let's denote the given angle by α. The adjacent angle measure is π-α. At last, we admit that the corresponding angles of intersection with the transversal are equal.

& & & & & & & & & & & & & & 50 / 180-50 = 130

& & & & & & & & & & & & & & /
