B is the answer I think is correct
Answer:
31°

The upper and lower triangles are similar, because their bases are parallel.
This implies that their correspondent angles have the same measure: the correspondent angle of x is the 31° angle.
Answer:
15x + 25 = y
Step-by-step explanation:
$25 is a fixed cost and will have to be paid if the plumber comes and $15 times the number of hours it takes to do the repair is the variable cost. 'x' in this case is the number of hours. So the equation will be 15x + 25 = y
