A guy wire is attached to the top of a pole. The other end of the guy wire is staked in the ground 29 feet from the base of the pole. How tall is the pole, if the guy wire is 73 feet long? Round to the nearest tenth.

This calls for the Pythagorean Theorem.
a^2 + b^2 = c^2
29^2 + b^2 = 73^2
841 + b^2 = 5,329
b^2 = 4,488
b = 66.99 = 67 feet
