Answer:

67 degree

Explanation:

The velocity of sound in air is given by the equation


v=20√(273+t)

where v is the velocity in meters per second and t is the temperature in degrees Celsius.

Given the velocity of sound in air is 369 that is our 'v'

We need to find out 't'


369=20√(273+t)

Divide by 20 on both sides


18.45=√(273+t)

Take square on both sides


18.45^2 = 273+t

340.4025= 273+t

Subtract 273 on both sides

67.4025 = t

Now round to nearest degree

t= 67 degrees
