Answer:
Step-by-step explanation:
Given: Angle 2 = 120, Angle 5 = 60, P is the transversal.
Image: Provided below
Solution:
Here, Angle 2 is given to be 120.
As Angle 2 and Angle 1 form a linear pair, the sum of the angles must be 180.
Angle 2 + Angle 1 = 180
120 + Angle 1 = 180
Angle 1 = 180 - 120
= 60
But, Angle 5 is given to be 60.
Thus, Angle 1 = Angle 5 = 60As the corresponding angles are equal, m is parallel to n.
