  • A) There are three more angles with the same measure.
  • C) The rest of the angles measure 122°.
  • E) Four of the angles measure 122°.

==========================================================

Step-by-step explanation:

I recommend drawing out a diagram as shown below. Angle 1 is 58 degrees.

Angle 3 is also 58 since the two angles are congruent vertical angles.

Angle 5 is equal to angle 1 due to them being corresponding angles (this only works if the lines are parallel)

Angle 8 is congruent to angle 5, for similar reasonings with angle 3 above.

So that means we have three additional angles that are 58 degrees: angle 3, angle 5, angle 8

-------------------

The rest of the angles are 122 as the diagram shows. We have four angles that make up the rest of the angles. Angle 2 and angle 1 add to 180, so

x+y = 180

58+y = 180

y = 180-58

y = 122

And you'll find the other unknown angles fit this pattern as well. Or you could use corresponding angles and vertical angles to fill out the rest of the diagram.
