Answer for the first blank is 6
Answer for the second blank is 8
----------------------------------------------------
Step-by-step explanation:
Angle 2 and angle 6 are corresponding angles because they are both on the top side of their respective parallel line pair, and they are on the right side as well. Since r || s, this means the corresponding angles are congruent, ie the same measurement.
Angle 5 is vertical to angle 8. Any two vertical angles are congruent. Vertical angles are such that they form when you cross two lines. The angles are directly opposite one another as is the case in angle 5 and angle 8.
Another vertical pairing is angle 6 and angle 7, which is just another example.
