A guy wire is 14 m long. It is attached to a TV tower 12 m high.
The guy wire is fastened to a stake in the ground.
How far is the stake from the base if the TV tower?

c2 = a2 + b2

 

c2 = 142 + 122

    = 196 + 144

    = 340

c = √340

   = √4 * √85

   = 2√85

x^2 + 12^2 = 14^2

x^2 = 196 - 144 = 52

x = sqrt(52) = 2 sqrt(13)m
