Question 1137283
The relationship between the​ cone's vertex​ angle, theta​, and the Mach​ number, M, of an aircraft that is flying faster than the speed of sound is given by
sine theta Over 2 equals 1 Over M
If theta equals pi Over 4
{{{(pi/4)/2 = 1/m}}}
{{{pi/8 = 1/m}}}
{{{pi*m = 8}}}
m = {{{8/pi}}}
m = 2.546 Mach
