Well, you know just by looking at it because it ends in an even number. Like, the greatest common factor of 4 is 2, 1.) Because no other number can "go into it," and 2.) Because it's even.
Explanation:
So, I know a lot of people won't do it this way, but this is how I would do it.
First, multiply each expense by eight (eight for the eight days)
$55 x 8 = 440
$25 x 8 = 200
$129 x 8 = 1032
Next, take the three answers and add them together:
440 + 200 + 1032 = 1672
Lastly, divide 1672 by four (four for the four friends)
1672/4 = 418
There you go! Here is your answer. Each friend paid $418
Hope I helped! :D

What question are you asking?
The exterior angle is supplementary to the adjacent angle (they form a linear pair) and is the sum of the two angles in the triangle that are not adjacent to it. For example, in number 2, the exterior angle is 28+40=68 degrees. You can use the other method to check. 68 degrees is supposed to be in a linear pair with 112 degrees, which it is. So the answer to number 2 would be 68 degrees.
