Mrs. johnson's first test's data: 59, 22, 87, 44, 96, 38, 70, 85, 79. what is the value of q1? (remember, the median for the four numbers, 22, 38, 44, and 59, is between 38 and 44. to find the median between two numbers, you take the average of those two numbers.)

The complement of an angle is one-sixth the measure of the supplement of the angle. what is the measure of the complement angle?
