Two intersecting lines create four angles, numbered 1, 2, 3, and 4, where ∠4 is adjacent to ∠1 and ∠3 , and m∠2=110° . Which other angle has a measure that is also equal to 110° ?

Since angles 1 and 4 are adjacent and Angle 4 is equal to Angle 1, we can conclude that Angle 1 will also have a measure of 110°.
