Remember that \sin(\theta) = \cos(90^\circ - \theta)

Thus, we can solve for x.
x + 22 = 90 - (2x - 7)
x + 22 = 97 - 2x
3x + 22 = 97
3x = 75
x = 25

valentina_108 [34]

Answer: The most appropriate measure of center is the median.

  • Mean is the best measure to represent the center of the data but when data have outliers it gets affected badly.
  • In that case, we use the Median as the best measure of center.

The given data is 12 10,9,68,12 .

As it can be seen that, the data have extreme value 68 ( called outliers).

In this case, we will use the Median as the best measure of center.

So, the most appropriate measure of center is the median.
