Answer: 108 degrees
============================================================
Explanation:
Angle ABC is given to be 90 degrees. By the converse of Thales Theorem, we know that AC is a diameter of the circle.
If we draw a line from A to C, it will pass through the center of the circle.
Therefore, arc AC is 180 degrees as this is half the distance around the circle.
minor arc AD = 72
minor arc CD = x
(minor arc AD) + (minor arc CD) = arc AC
72+x = 180
72+x-72 = 180-72
x = 108
minor arc CD is 108 degrees

Answer: The percent of US adults spend above 29 hours per month on PC internet = 50%
Step-by-step explanation:
Given: , US adults spent on average 29 hours per month using the PC internet.
As the me spent on the PC internet follows a normal distribution.
And there is 50% of the population lies above the mean and below the mean.
Then, the percent of US adults spend above 29 hours per month on PC internet = 50%
