Final answer:
The angle between the two guy wires attached to an antenna is found by subtracting the angle of one wire from that of the other, yielding 0.11 radians as the result.
Step-by-step explanation:
The question asks to find the angle between two guy wires attached to an antenna. Since the angles are given with respect to the vertical (antenna), to find the angle between the two wires, we subtract the smaller angle (α = 0.31 radians) from the larger angle (β = 0.42 radians).
To calculate the angle between the two guy wires, the formula will be β - α, which in this case is 0.42 radians - 0.31 radians. Therefore, the angle between the two guy wires is 0.11 radians.
