The figure shows a rectangular lawn at a civic center. Over time, people have cut across the lawn to walk from the library to city hall and made a straight path in the lawn, as shown. What is the measure of ∠1 in the figure?

I'm not sure but i think it's 1670km/h

$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
