Answer:
109°
Step-by-step explanation:
x+48+23=180
x=180-71
<h3>x=109°</h3>
Answer:
C. 
Step-by-step explanation:
We have been given an image of two parallel lines crossed by a transversal. We are asked to find the measure of m.
We can see that angle that measure 78 degrees and angle m are consecutive interior angles.
Since we know that consecutive interior angles are supplementary, so we can set an equation to find the measure of m as:



Therefore, the value of m is 102 and option C is the correct choice.
