Answer:
Step-by-step explanation:
The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.
We can add up that and the other arcs to 360.
Plug in 2 for WX.
Recall Euler's theorem: if , then
where is Euler's totient function.
We have - in fact,
for any
since
and
share no common divisors - as well as
.
Now,
where the are positive integer coefficients from the binomial expansion. By Euler's theorem,
so that
