An engineer, a mathmatician and an arts graduate

An engineer, a mathmatician and an arts graduate were given the task of
finding the height of a church steeple (the first to get the correct solution
wins a $1000).


The engineer tried to remember things about differential pressures, but
resorted to climbing the steeple and lowering a string on a plumb bob until it
touched the ground and then climbed down and measured the length of the string.


The Mathematician layed out a reference line, measured the angle to the top of
the steeple from both ends and worked out the height by trigonometry.


However, the arts graduate won the prize. He bought the vicar a beer in the
local pub and he told him how high the church steeple was.
