Answer:
D. 110°
Step-by-step explanation:
we know that
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.
When the two lines are parallel Corresponding Angles are congruent
In this problem
The transversal line is t
The two lines that are crossed by the transversal are line l and line m
Lines l and m are parallel
therefore
[tex]m\angle 1=m\angle 2=110^o[/tex] ----> by corresponding angles
