Here is a problem I found which is from a math class in 1957:

A man is standing due East of a tower and notes it subtends an angles of 45 degrees with the tower.
He walks South 42.4 feet and the subtended angle is 30 degrees.
How tall is the tower?

(You are only allowed to use only pencil(pen) and a paper)
