Which angles are corresponding angles? question 18 options: none of these ∠7 and ∠3 ∠3 and ∠11 ∠8 and ∠3

For now, let's assume we can rule out choice A. 

Angles 3 and 7 are vertical angles. So we can rule out choice B

Angle 3 and angle 11 are corresponding angles. They are on the topside of their adjacent parallel horizontal line. They are also on the left side of the transversal cut line d. The answer is choice C. 

Angles 3 and 8 are not corresponding angles. Corresponding angles are not adjacent to one another. In other words, they do not share a common vertex.

$250 deductible means jane must pay the first $250 of her bill. so the insurance company paid = (80% of bill) - deductible = (0.8 x $2550) - $250 = $2040 - $250 = $1790 and jane's cost is = (bill) - (insurance payment) = $2550 - $1790 = $760
