34 degrees the angles are opposite side exterior angles of two parallel lines with a line that intersects both. The opposite side exterior angles will always be equal to each other
If '1' is 34 '3' is 34 too.(opposite angles). If '3' is 34 '5' is so too.(It's a rule, taught us as 'Z rule') If '5' is 34 '7' is so too(opposite angles again).
