which data set has a variation, our main absolute deviation, similar to the data set in the given dot plot?​

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

i just took the test, the correct answer is .. 31.5 in.

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 option is the answer.
