A telephone tower casts a 50-foot shadow that makes a 48° angle with the ground. If Fiona wants to find the length of the cable that secures the tower to the ground, how should she set up the problem?
Option #1: cos48°=x50
Option #2: cos48°=50x
Option #3: cos50°=50x

Option #2.
Reason: Let x be the cable (hypotenuse). The horizontal distance (adjacent) is 50 ft and the angle with the ground is 48°, so cos(48°) = adjacent/hypotenuse = 50/x.
