Needed asap pl a construction crew wants to hoist a heavy beam so that it is standing up straight. they tie a rope to the beam, secure the base, and pull the rope through a pulley to raise one end of the beam from the ground. when the beam makes an angle of 40° with the ground, the top of the beam is 8 ft above the ground. the construction site has some telephone wires crossing it. the workers are concerned that the beam may hit the wires. when the beam makes an angle of 60° with the ground, the wires are 2 ft above the top of the beam. will the beam clear the wires on its way to standing up straight? explain.
