Reggie's family is planning to put an above ground swimming pool in their back yard. Their yard is a 49 ft by 92 ft rectangle and the pool will be a circle with a diameter of 20 ft, as shown below. They will fill the rest of their yard with grass. Approximately how many square feet of their yard will be grass?

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
