Answer:

angle 1 = 118 deg

angle 2 = 62 deg

Explanation:

To find angle one you must know that angles 1 and 118 deg are alternate angles. Therefore since these lines are parallel, angles 1 and 118 are equal.

To find angle 2 to you must know that angle 1 + angle 2 = 180.

angles on a straight line always equal 180 deg

therefore:

180

118 -

62 deg

hope this helps :)

Answer:

m<1 = 118°

m<2 = 62°

Explanation:

The horizontal lines are parallel.

Angles 1 and 118° are alternate interior angles of parallel lines cut by a transversal, so they are congruent.

m<1 = m<2 = 118°

Angles 1 and 2 are a linear pair, so they are supplementary. That means that their measures add to 180°.

m<1 + m<2 = 180°

118° + m<2 = 180°

m<2 = 62°
