What is the answer to this problem?

B.) Transitive Property of Congruency; If parallel lines have a transversal, then alternative interior angles are congruent.

Step-by-step explanation:

Alternate interior angles are the two angles that are inbetween the parallel lines but are on opposite sides of the transversal.  Angles 4 and 5 are alternate interior, and therefore, they are congruent.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
