Question

I need help with this geometry

Answer 1

100°

Explanation:

Alternate angles on a cross section of a parallel line are equal. Because 80° is above it, it needs to be the opposite angle. angles on a straight line are 180° so 80+100=180°

Answer 2

i think its 100

Explanation:

180-80=100 and since the to one is vertical to where the question mark is , it's also 100
