The Attempt at a Solution
f = 90.0 MHz
λ = (3E8)/(90E6) = 3.33 m
Let x, y, r represent the following
[PLAIN]http://img852.imageshack.us/img852/5836/questionso.png
Eq. 1
(x) - (r-x) = λ
Eq. 2
(x+y)-(r-(x+y)) = 0.5λ
2x + 2y - r = 0.5λ
Somehow I have to find the distance y. I am not exactly sure how I would go about solving this because I have 2 sets of equations (one with 2 variables and other with 3 variables).
Thanks,
