Answer:
C. ∠10
Explanation:
A theorem states that the two angle that are in the same side and are opposite to each other, they add up to 180°, which is supplementary.
Hey there, again! :D
Since the angle measuring 38 degrees is adjacent to m<1, it will equal 180 degrees.
180-38= 142
m<1= 142 degrees
I hope this helps!
