Here is your answer ⤵⤵⤵

A source of sound S emitting waves of frequency 100 Hz and an observor O are located at some distance from each other.

The source is moving with a speed of 19.4 ms⁻¹ at an angle of 60° with the source observer line as shown in the figure.

The observor is at rest. The apparent frequency observed by the observer is (velocity of sound in air 330 ms⁻¹)

HOPE IT HELPS YOU ☺☺ !!!
