Answer:

Step-by-step explanation:
We first translate the statement into an equation:

Then we simplify:

Answer:
4.6
Step-by-step explanation:
The total measure of the interior angles of each figure will be:
180 (n-2) = 180 (4 - 2) = 360
Now add all those angles and set them equal to 360.
41 + 133 + 86 + x = 360
x is the unknown angle.
260 + x = 360
x = 100
The missing angle that is Not labeled in any of the figure is 100°
Hope this helps :)
