Since the blades are equally spaced, the question is the same as "How many degrees are between each blade?"
OpenStudy (andrewkaiser333):
is it 72°?
OpenStudy (andrewkaiser333):
for each i think it is 72°
OpenStudy (ddcamp):
@AndrewKaiser333 Why do you think it is 72°?
OpenStudy (andrewkaiser333):
360°/5=72°

Yup, that's the right reasoning and answer.
OpenStudy (andrewkaiser333):
just did the math the other one was a guess just woke up and you said it is equally spaced
OpenStudy (andrewkaiser333):
just had coffee so am awake now and can think sorry for the first answer which was 60° it is actually 72°.
OpenStudy (andrewkaiser333):

OpenStudy (andrewkaiser333):
