The speed of sound is approximately 340 m / s. how long will it take for the sound to travel from the batter to a spectator who is seated 30 meters away? how long will it take if the spectator is 150 meters away?

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

e) none of the above because the measure of angle cba is 101°
