Answer 1

i say 58

Answer 2

58 is correct via symmetry!

Answer 3

because of the look of it it look like the same leneth

Answer 4

length has nothing to do with it...there is simply 180 degrees on a straight line...
for example the angle directly to the right of "58" would be 180-58 or 122 degrees

so if you wanted to know the angle directly to the left of X, it would also be 122 degrees because of symmetry...make sense?

Answer 5

Which pairs of angles are alternate exterior angles?
