ANSWER:
For the first picture, it is the first answer. This is because of the Exterior Angle Theorem.
For the second picture, use the Exterior Angle Theorem again, but this time, solve for x.

The m∡B = 39°
I think .. correct me if i’m wrong
1. 3x+75=165
2. 3x+200
The population increases by a factor 1.0167 every year so the require figure is:
103 * 1 . 0167^5 = 112 million
The next number in this pattern should be A)28
