**Henry**, Saturday, October 19, 2013 at 5:45pmThe 1st(closest) car:

X1 = Distance from tower.

A1 = 60o = Angle between X1 and hyp.

The 2nd car:

X2 = Dist. bet. the 2 cars.

X1+X2 = Dist. from 2nd car to tower.

A2 = 30o = Angle bet. (X1+X2) and hyp.

tan 60 = 50/X1

X1 = 50/tan 60 = 28.87 m.

tan 30 = 50/(X1+X2)

X1+X2 = 50/tan 30 = 86.60 m.

28.87 + X2 = 86.60

X2 = 57.73 m.
