The two angles are related to supplementary.
Relation of angle:
Given angle:
\(\to 60^{\circ}\\\\\to 120^{\circ}\\\\\)
Calculating the sum of angle:
Sum of angle\(= 60^{\circ}+120^{\circ} = 120^{\circ}\)
Since the sum of supplementary is \(180^{\circ}\) and really you're when you combine the different sides together. These angles are those that add up to \(180^{\circ}\).
Therefore, the final answer is "Option A".
