Question Which statements are true about Gretchen’s adjusted data set?

The center moved farther from the center of Manuel’s data set.
The spread values are farther from the spread values of Manuel’s data set.
The center moved closer to the center of Manuel’s data set.
The data set is approximately symmetric.
The spread values are closer to the spread values of Manuel’s data set.
The data set is skewed left.

The center moved closer to the center of Manuel’s data set

The spread values are closer to the spread values of Manuel’s data set.

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
