Anne wants to tie a support line from the top of a 50 foot radio tower to an anchor spot 30 feet from the towerâ€™s base. Approximately how long will the line need to be?

This makes a right angle triangle  and can be solved by the Pythagorean Theorem.
a^2 + b^2 = c^2
50^2 + 30^2 = c^2
2500 + 900 = c^2
3400 = c^2
58.3 = c
