Question

a tv station is constructing an 8 foot tower fir a new antenna. the tower will be supported by 3 cables, each attached ti the too of the tower and to.points on the roof of the building that are 10 feet from the base of the tower. find the total length of the three cables

Answer 1

By using the pythagorean theorem, you can create a right triangle that allows you to see the length of a single cable. 

8^2+10^2=l^2

Length (l) = 12.8 (when rounded to the nearest tenth). 

Then you can multiply by 3 and get 38.4ft.
