Arow of sprinkler's is to be installed parallel to and 4.5 feet away from the edge of flower bed. each sprinkler waters a region with a 6 foot radius. how far apart should the sprinkler's be placed to water the entire flower bed with the least possible overlap of coverage?

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
