Answer is C (108).

All 4 angles combined are always 360 degrees. In this case if you add 2 angles combined thehy are always 180 degrees.

If we know angle 1 is 72 than angle 3 is 180-72
And 180-72 =108

Since Angle 1 and 3 are vertical angles, they are congruent.

In this case, because Angle 1 is 72°, Angle 3 is 72°, or D.

our goal is to run a mean of 45 minutes per day for a week. For the first six days, you run 38, 40, 40, 42, 43, and 50 minutes.

Answer:

62 minutes.

Step-by-step explanation:

To find the mean, you need to <u>add</u> together all of your values (the minutes) and <u>divide</u> them by the number of values (how many sets of minutes given).

So, choosing to add 62 minutes:

38 + 40 + 40 + 42 + 43 + 50 + 62 = 315

There are 7 sets of minutes in total, so we then divide 315 by 7.

315/7 = 45 minutes

Therefore, running 62 minutes on the seventh day would cause you to run a mean of 45 minutes per day for the week.
