The sum of the “full” angle = 360 °. Those. full turn. If the sum of the three angles formed at the intersection of two straight lines is 318 °, then some fourth angle = 360-318 = 42 °.
One of those three corners is vertical with an angle of 42 °. Those. is also 42 °. One of the remaining two angles is adjacent to an angle of 42 °. 180-42 = 138 °. Finally, the last angle will be 138 ° vertical and equal to 138 °.
Answer: two angles of 42 °, two angles of 138 °.
