I think it's b but I may be incorrect
The answer is: "42" .

Explanation:
_____________________________________
From the stem-and-leaf plot provided, we can write the following values from the data set, from least to greatest:
____________________________________
{15, 18, 46, 50, 50, 50, 50, 57} ;
____________________________________
To calculate the mean, we take the sum of all the values in the data set; that is, we add up all the values in the data set; and we divide that sum total by the number of values in the data set.
In our data set, we have EIGHT (8) values.
To calculate the mean:
_________________________
{15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 = the mean {our answer}.
________________________________________________________
→ {15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 =
→ {336} / 8 = 42 .

The answer is: " 42 " .

Hope this explanation is helpful.
Answer: 1. False. [∠XFG is lying between the one side and the line extended to the next side of the triangle, therefore it is an exterior angle.]
2.True. [∠EFG is lying between the two sides of the ΔEFG, therefore it is an interior angle of the triangle]
3.True. [∠FEZ is lying between the one side and the line extended to the other side of ΔEFG ]
4.False. [∠YGE is a straight line it is between the one side and the line extended to the same side ∴ it cannot be an exterior angle of the triangle ]
5. True.[∠EGF and FGY together make a straight line therefore they are supplementary angles]
6.False.[∠FEG and ∠FGE are both the interior angles of a triangle and we know that for supplementary angles they should lie on the same line or together make a straight line]
I can't find the answer tonight. I accidentally left my textbook in school.
Answer:
i think its a 90 degree triangle angle to the right
