Concept used:
Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°
Calculations:
In a triangle, if angle A measures 60°, the measure of the adjacent angle to A is 120°.
These angles are called supplementary angles.
Hence, Option 2 is Correct.

Supplementary Angles
An angle that measures 60° is known as angle A in a triangle. The adjacent angle to angle A in a triangle is called a supplementary angle.
Definition of Supplementary Angles:
- Supplementary angles are two angles whose measures add up to 180°.
- In a triangle, the sum of all three angles is always 180°.
Explanation:
- Since angle A measures 60°, the sum of angle A and its adjacent angle must be 180° in a triangle.
- Therefore, the measure of the adjacent angle to angle A would be 180° - 60° = 120°.
- This means that the adjacent angle to angle A in the triangle is a supplementary angle.
Conclusion:
- In this scenario, the measure of the adjacent angle to angle A in the triangle is 120°, and it is classified as a supplementary angle.
