You offer senior citizens a 20 percent discount on their meal prices served at your cafeteria. assuming that an average of 150 senior citizens eat daily at your cafeteria and that the average price of their meals before discount is $5.95, how much total discount do you give on an average daily basis? a. 1,79 b. 17.85 c. 178.50 d. 1785.00

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
