Answer:

1. <1 and <8

< 2 and <7

2. 60°

Explanation:

1. When two lines are cut by a transversal, the pairs of angles on either side of the transversal and outside the two lines are called the alternate exterior angles.

2. If two parallel lines are cut by a transversal, then the alternate exterior angles formed are congruent.

Congruent angles are angles with the same measurement.

Answer:

see explanation

Explanation:

∠ 1 and ∠ 8 , ∠ 2 and ∠ 7 are alternate exterior angles

They are on opposite sides of the transversal and outside the parallel lines

Given ∠ 1 = 60° , then

∠ 8 = 60° ( alternate exterior angles are congruent )
