228.5 I believe. 14/49 is 3.5. 18+7 is 25x9 is 225. 225+3.5 would be 228.5
I’m pretty sure it is (7, 2)
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°
Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°
The value calculated by adding all the values of in a data set and dividing the sum by the number of values → Mean
The middle value when all the values are in order from least to greatest → Median
The value that appears most often in a data set → Mode
Hope this helped :)
Well, all we have to do is add, so:
6 + (-47) =
6 - 47 =
-41
