Question

17. In the diagram below, lines I and m are parallel.

Answer 1

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

$m\angle 1=m\angle 2=110^o$ ----> by corresponding angles
