After a very intense, multiday storm, your 1,375 square-foot basement has flooded to a depth of 18 inches. That's equivalent to about 15,425 gallons of water! You haven't been able to get a water removal company to come since they are overloaded with jobs. Your boss suggests that you borrow the company's submersible utility pump and do the job yourself. It can pump 1,200 gallons of water per hour. To the nearest hour, how long will it take to drain your basement?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
