Answer:
Complementary angles are angles that = 90°
Whatever y° is, You subtract that number from 90°
For ex:
y°=25
90° - 25° = 65°
So, Angle B would equal 65° in this example.

Since lines a and b are parallel, we can assume that y,u,x, and s are equal and z, r, and t equal 158. We know that angles t and s are supplementary angles, so we can find angle s by subtracting 158 from 180. 180-158=22. Angle s is equal to 22.
