Angular distributions of extensive air showers with different number of charged particles in the range ${2.5\cdot10^5}$-${4\cdot10^7}$ are derived using the experimental data obtained with the EAS MSU array. Possible approximations of the obtained distributions with different empiric functions available in literature, are analyzed. It is shown that the exponential function provides the best approximation of the angular distributions in the sense of the $\chi^2$ criterion.
