Congruent - having the same angle measure
Supplementary - both angles measure 180 degrees
If angle b is congruent to angle a and the supplement of angle b is 22, you would take 180-22, which is equal to 158 degrees. If angle a is congruent to this, meaning it has the same measure, then it would also be 158 degrees. This is your final answer.
Hope this helps!
