Answer:
1) 48 and C) It corresponds to the 48-degree angle.
Explanation:
Seeing the parallel lines k and l, and the transversal line m, we have that 48° and angle 1 are corresponding angles because k and l are parallel, then, the angle formed with the same transversal line will have the same measure.
So, the measure of angle 1 is 48 (option 1) and the reason is C) It corresponds to the 48-degree angle.
