The mean is all the numbers added up and then divided by how many x's there are. In this case, it's 27+29+32+32+36+38+38+42+42 = 345, then you divide it by 9 (the number of x's) and you get 38.33
The median you be the number in the center of the string of numbers, 36 in this number line, because there are nine numbers total and 36 has four numbers on each side
27, 29, 32, 32, 36, 38, 38, 42, 42
The range is the biggest number minus the smaller number, 42-27
So the range is 15

Answer:
45:36 is the answer.
Step-by-step explanation:
Divide 81 by sum of ratio.

45 : 36
Check: 45+36=91
These angles are called corresponding angles
