Since we know that the angle 130 degree is between the incident sound wave and the reflected sound waves and the total angle is 180 degree when we subtract 180 - 130 we get 50 which is the sum of the angle of incidence and angle of reflection since we know that both are equal then we can say 2x its equal to 50 and X will be 25 Hope it helped you
