Question

Two lines intersect and two of the vertical angles measure 115°. What is the measure of the other two vertical angles?

65°
85°
90°
245°

Answer 1

The measure of the other two vertical angles is 65°.

Explanation:

The measure of supplementary angles is 180°. Therefore, as two of the vertical angles equate to 115°, their supplements must create a total sum of 180 when combined. 180-115=65
