The situation that is best modeled by a discrete graph is: a. the daily records of the distance of each hotel from home during a cross-country trip. b. the height of a wave over time. c. the speed of a motorcycle over the distance it travels. d. the body temperature of an athlete during a workout.

Since you only record a result each day for selection A, but you record results essentially continuously for B, C, D, the best choice is ...

... A. the daily records of the distance of each hotel ...

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
