Alternating and Linear Pair Angles

Hard Geometry Lines And Angles

In a geometric diagram, two lines (line L and line M) are intersected by a transversal line T, creating several angles. If the measure of angle 1 is given as $50^{ ext{o}}$, and angle 2 is an alternate interior angle corresponding to angle 1, what is the measure of angle 2?

Additionally, if angle 3 is adjacent to angle 2 and forms a linear pair with it, what is the measure of angle 3?
