In the figure if m ∠ 12 = 74 ° . m\angle12=74\degree. m ∠ 1 2 = 7 4 ° . Find m ∠ 4 m\angle4\ m ∠ 4 and give proper reasoning.

74 ° 74\degree 7 4 ° because they are corresponding angles.

106 ° 106\degree 1 0 6 ° because alternate interior angles.

106 ° 106\degree 1 0 6 ° because corresponding angles.

74\degree 7 4 ° because they are consecutive interior angles.

If m ∠ 10 = 53 ° m\angle10=53\degree m ∠ 1 0 = 5 3 ° find m ∠ 4 m\angle4 m ∠ 4 and give proper reasoning.

53\degree 5 3 ° because alternate exterior angles.

127 ° 127\degree 1 2 7 ° because alternate exterior angles.

127\degree 1 2 7 ° because alternate interior angles.

53 ° 53\degree 5 3 ° because consecutive interior angles.

What is m ∠ Y m\angle Y\ m ∠ Y if m ∠ X = 72 ° m\angle X=72\degree m ∠ X = 7 2 ° ?

m ∠ Y = 108 ° m\angle Y=108\degree m ∠ Y = 1 0 8 ° because consecutive interior angles.

m ∠ Y = 72 ° m\angle Y=72\degree m ∠ Y = 7 2 ° because alternate interior angles.

m ∠ Y = 108 ° m\angle Y=\ 108\degree m ∠ Y = 1 0 8 ° because corresponding angles.

m ∠ Y = 72 ° m\angle Y=72\degree\ m ∠ Y = 7 2 ° because alternate exterior angles.

Solve for x and give proper reasoning.
