| 1. Since at the intersection of two straight lines, two pairs of vertical angles are formed, then the second angle will also be equal to 49˚.
2. Find the second pair of vertical angles 180˚ – 49˚ = 131˚, that is, each angle of the second pair is equal to 131˚.
Answer: the undeveloped angles formed at the intersection of two straight lines are equal to 49˚, 131˚, 49˚, 131˚.
