Both lines form four angles. Two are congruent, and the other two are also congruent.
In this line, we have that 22 degrees and (5x + 3) degrees are supplementary angles (they sum 180 degrees).That is:
22 + (5x + 3) = 180
22 + 5x + 3 = 180
22 + 3 + 5x = 180
25 + 5x = 180
Subtracting 25 at both sides:
25 - 25 + 5x = 180 - 25
0 + 5x = 155
Dividing at both sides by 5:
(5x / 5) = (155/5)
x = 31
Therefore, this angle is 5x31 + 3 = 155 + 3 = 158 degrees.
