An adventurous archaeologist crosses between two rock cliffs by slowly going hand-over-hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope . The rope will break if the tension in it exceeds 2.95×10^4 , and our hero's mass is 86.2 .

What is the smallest value the angle can have if the rope is not to break?
