[TowerTalk] Phasing lines

Hi All

If 90 degrees is 360/4 (1/4 wave) then is 72 degrees 360/5 (1/5 wave)?

Would that make a 72 degree phasing line 23.4 feet (133/5 * .88)?

Then an 80 degree phasing line would be 26.1 feet (133/4.5 * .88)?

I am actually trying to figure 80 and 71 degrees lines for 40 meters using 
RG8X.

My high school math is buried somewhere in the back of my brain.

If this is true, how can I find which frequencies these would be a 1/4 wave 
at so I could use the analyzer to cut them to length?

I want to make phased verticals with an 80 degree feedlines with a 71 degree 
phasing line.  73
