I'm not sure what the question is, but I can help find the measure the each angle.
Angles G, c, H, and e all equal 75°
Angles F, d, and l equal 105°
A straight line is 180°, so all you have to do is subtract 75 from 180.
Angles across from each other are congruent, and angles next to each other are supplementary, meaning they add up to 180.
I hope that helps!
