The angles of a triangle must add to 180. We know 2 of the angles, so by subtracting them both from 180 we can find the remaining angle.

180 - 75 - 40 = 65

The 65 degree angle and the angle we are looking for are supplementary angles. This means they add to 180.

180 - 65 = 115

The answer is 115.

Julia measured the high temperature in her town for one week. Using the chart below, find the mean absolute deviation for the hi

Alex

Finding the mean is you have to add it all up:
49+55+52+46+47+42+38= 328
The divide it by the amount of numbers so, 329/7= 47.
Subtract 47 from every number then, but even if you get a negative number you gotta keep it a positive so just ignore it if you get a negative answer when subtracting, once you do that you would add up those answers you got so;
2+8+5+1+0+5+9= 30
Then divide it again, 30/7
Which then you get the M.A.D which is 4.3, rounded to the nearest ten.
