Answer 1

Red: 108

Blue: 55

Explanation:

You can see that the 2 sidelines are parallel. This means that the line from purple to blue is a transversal or a line that passes through 2 parralel lines. The line from red to green is also a transversal.

This means that on the transversal, the angles must be supplementary, or add up to 180.

For purple to blue, we have 125 + x = 180. So x is 55.

For Red to green, we have 72 + x = 180. So x is 108
