Homework Statement

Find dss, dsr and thus hs.
Homework Equations
trig
The Attempt at a Solution
dss = hs/(sin[θ])
dsr = hs/(sin[∅])
dss = 3.059/(cos[θ])
dsr = 47.191/(cos[∅])
θ = arctan(hs/3.059)
∅ = arctan(hs/47.191)
I have tried many times to solve this; usually by substituting the last two equations into the first 4 and trying to solve but without success.
The problem is to do with ISO9613 where Z (path difference between dss+dsr and d) = 7.81 m and d = 50.25 m.
