Question

1)60°.
2)80°.
3)100°.
4)None of the choices are correct.

Answer 1

80

Explanation:

If M line 1 is 0, then M L 2 is also 0 because of the traverse angle theorem( I think)

You can prove this by plugging in x for line 1 and just going around the whole Diagram.

Answer 2

Since this is a transversal, we know that they're corresponding interior angles.

Therefor, angle 1 is congruent to 2.

The answer would be 80.
