Aswimming pool is 15 by 30 feet and 5 ft deep if a gallon of paint can cover 250 square feet how many gallons of paint?

well the answer to that is xoxoxo

step-by-step explanation:

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

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
