Can someone me & explain, ?

Put the numbers in the data set in order from smallest to largest:

44, 45, 45, 47, 49, 50, 50, 51, 55, 55, 55, 56

The smallest number is 44, the largest is 56, so the outside lines need to be above those numbers.

Both A and B have that.

Now find the median ( the average of the middle two numbers)

The middle two numbers from the list are 50 and 50 so the median would be (50 +50) /2 = 100/2 = 50

The middle line inside the rectangle needs to be above 50.

This makes the answer A.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
