Find all undeveloped angles formed at the intersection of two straight lines, if the sum of three of them is 307 degrees.
| August 14, 2021 | education
1. The first undeveloped angle formed at the intersection of two straight lines will be equal to 360˚ – 307˚ = 53˚.
2. Since at the intersection of two straight lines two pairs of vertical angles are formed, then the second angle will also be equal to 53˚.
3. Find the second pair of vertical angles 180˚ – 53˚ = 127˚, that is, each angle of the second pair is equal to 127˚.
Answer: the undeveloped angles formed at the intersection of two straight lines are equal to 53˚, 127˚, 53˚, 127˚.
