Answer:
79 and 101
Explanation:
These angles together form a straight angle that equals 180. This means adding their measures together is 180 degrees. So 2x -1 + 3x - 19 = 180. Solve for x.
2x - 1 + 3x - 19 = 180
5x - 20 = 180
5x = 200
x = 40
Substitute x = 40 into each expression to find the measure of each angle.
2x - 1 becomes 2(40) - 1 = 79
3x - 19 becomes 3(40) - 19 = 101
