Answer 2

2) 50

Explanation:

Basically, supplementary is when you add two angles, they should equal 180 degrees. In this picture, we can see that the bottom two rays form a straight line, indicating that it is a 180-degree angle, also. Great way to visualize, by the way. Well, 180 - 130 is 50 degrees, so x is equal to 50 degrees.
