Final answer:
The distance from point A to the transmitter is approximately 2.49 miles.
Step-by-step explanation:
To find the distance from point A to the radio transmitter, we can use trigonometry. We know the hearing bearing from point A is 47.7 degrees. Since we have a right triangle with the line joining points A and B as the hypotenuse, we can use the sine function to find the length of the side opposite the angle. Setting up the equation, sin(47.7) = length of opposite side / 3.46. Rearranging the equation, length of opposite side = 3.46 * sin(47.7). Calculating this value, we find that the distance from point A to the transmitter is approximately 2.49 miles.
