Solve for x using pythagorean theorem (round to nearest hundredth

Set up equation: x^2+9^2=26^2
work out values: x^2+81=676
isolate the x value (sub. 81 from both sides): x^2=595
get x by itself (take the square root of both sides): x=24.39

$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
