Answer:

A) (i) a = 95° (180 - 85), b = 85° (180 - 95), c = 85° (180 - 95), d = 95° (180 - 85)

A) (ii) a = 103° (180 - 77), b = 77° (180 - 103), c = 103° (180 - 77), d = 77° (180 - 103)

B) (i) 95 + 85 + 85 + 95 = 360°

B (ii) 103 + 77 + 103 + 77 = 360°

Tip: Angles on a straight line add to 180°

Hope this helps!
