Answer:
what type? if right then
7^2+16^2=23^2
49+256=529
305≠529
so its not a right triangle
Step-by-step explanation:
<span> the mean absolute deviation is the average absolute deviation from the mean and is a common measure of forecast error in time series analysis. </span>
I believe that because there are 180 degrees in a triangle, and ACB is a triangle, you can add up two of the angles and subtract that from 180. So
30+50=80 and 180-80=100, that mean the angle above angle 1 is 100. And since angle one and that angle 100 are vertical angles, angle 1 = 100
You have to divide 397 and 8.
