Reasoning: Alternate interior angle theorem
The angles shown are inside the parallel lines, so they are interior angles. They are also considered alternate angles because they are on alternating sides of the transversal cut. Alternate interior angles are congruent when we have parallel lines like this.
A 30 hours per year
B 30X(100+20)%=36 per year
1.5 year later is 5.5 years
5.5X36=198 hours
