Answer:
53°, 127°, 127°
Explanation:
Two intersecting lines form two pairs of angles:
- Pair of vertical angles. They are opposite to each other and are equal
- Pair of adjacent angles which are supplementary angles and their sum is 180°
So if one of the angles is measured 53°, then the other angles are:
- 53°- vertical angle with the first one
- 180° - 53° = 127°
- 180° - 53° = 127°
