Let us take units in which the speed of light $c = 1$, and put c back in the final answer, in such cases where it is there, to make it easier to write formulae.

Let the incoming pion velocity direction be along X-axis, and neutrino direction be along Y-axis, then the 4-momenta of the pion and neutrino
p_pi = m_pigamma(1, beta, 0, 0),
p_nu = ...
This solution uses step by step calculations and formula to solve the given problems.
