Solve for x and y:
x =
y =

x = 15

y = 21

Step-by-step explanation:

*triangle sum theorem*

(6x - 11)° + (81)° + (x + 5)° = 180°

(7x - 6)° + (81)° = 180°

(7x)° + (75)° = 180°

(7x)° = (105)°

x = 15

*vertical angle theorem* *triangle sum theorem*

(6x - 11)° + (4y - 18)° + (y + 14)° = 180°

15

(79°) + (4y + y) + (14 - 18)°

(79)° + (5y - 4)° = 180°

(5y)° + (75)° = 180°

(5y)° = 105°

y = 21

14

Step-by-step explanation:

The mean absolute deviation of a dataset is defined as the average distance between each datav alue and the mean.

It is computed by formula:

average value of the data set

n=number of data values

=data values in the set

MAD=

=

=14

Hence, the mean absolute deviation of the set of data = 14
