Answer:
1. <1 = 133 (this is because 180 - 47 = 133)
2. <8 = 133 (this is because <8 is alternate exterior to <1, so they are congruent and equal)
3. <4 = 133 (this is because 180 - 47 = 133)
4. <5 = 133 (this is because <2 is 133 degrees and we know that it is corresponding with <6, so they are equal. subtract 47 from 180 and you get 133 degrees)
they're all 133 degrees! i hope this helps!
