A college conducts a survey of its humanities professors about the languages that they know, with the following results. They would like to choose a professor at random to interview. If no professors speak all three language types, what was the sample space in this study?

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

42

step-by-step explanation:

256/6=42

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
