mark as brainliest answer

The answer here would be D.

Step-by-step explanation:

When looking at the angle you can see that it is a straight line with a intersecting line. This tells you that you will have supplementary angles, or angles that add up to 180 degrees.

You can only have supplementary angles when they are on either side of a straight line that has been intersected.

Since supplementary angles have to add up to 180 degrees, and you already know that one part of the current supplementary angles is 50 degrees, you can do the math,

180-50=130

To get your answer of D. 130

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
