Answer:
The beam will clear the wires
Explanation:
First find length of the beam, b:
sin40 = 8/b
b = sin40(8) = 12.446 ft
Now find height of tip of beam, h, from ground when beam is at 60°:
sin60 = h/12.446
h = sin60(12.446) = 10.78 ft
The height of the wires = 10.78 + 2 = 12.78 ft
(Height of wires) - (length of beam standing up straight) = 12.78 - 12.446 ≈ 0.33 ft
The beam will clear the wires by about 4 "
