The sum of the 2 angles formed when two straight lines intersect is 78 degrees. Find the larger angle.

When two straight lines intersect, four corners are formed, two of which are acute, and two are obtuse, or vertical, equal to each other and adjacent 180 ° in total. If the sum of the angles is less than 180 °, they are vertical. Let’s answer the question of the problem.
(360 – 78) / 2 = 141 °.
Answer: 141 °.
