The sum of the three angles formed when two straight lines intersect is 280 degrees greater than the fourth angle. Find the four corners.
When two straight lines intersect, 2 pairs of vertical are formed, i.e. equal angles.
Hence, 2x + y = y + 280
2x = 280
x = 140
Then y = 180 – 140 = 40
Answer: 2 angles of 140 ° and 2 angles of 40 °
