a guy wire is 15m long. it supports a vertical television tower. the wire is fastened to the ground 9.6m out from the base of the tower

a) calculate the angle formed by the guy wire and the ground
b) calculate how far up the tower the guy wire attacks

1 answer

cos^-1(9.6/15) = angle formed by ground and wire

15^2-9.6^ = 132.84

√132.84 = 11.55 = how far up the tower the guy wire goes
