A tall h 115 ft antenna is held in place by guywires on sev

A tall (h = 115 ft) antenna is held in place by guywires on several sides. The angle of elevation of the guywire, is A = 56 degree, as shown in the figure below. What is the length of each guywire? Post Discussion

Solution

Let length of guywire be x

So, using trigometric ratios:

sinA = h/x

h = 115 ft

sin56 = 115/x

x =138.71 ft
