Answer:
well here you go
1= 129
2= 51
3= 129
4= 51
5= 129
6= 51
7= 129
Explanation:
since angle 51 is congruent to angle 2, they have the same measure which is 51. and if you look at it, angle 1+ 51 = 180 because they are supplementary angles. when you subtract 51 from 180 you get 129. for the other angles, look at the four on the bottom right side as a copy and paste of the four on the top left. basically meaning since 51 is congruent to angle 2 apply that same thing to angles 4 and 6. and since angle 1 is 129, that means angle 3 is 129 also. again, apply that same thing to angles 5 and 7.
sorry if its confusing, i get it
hope i helped :)
