Two straight-line railways intersect at point 
at an angle of 
. Inside this angle there is an airfield (point A) at distances of 
km and 
km from these roads. Find the locations of points 
and 
(places of loading and unloading cargo) on these roads so that the cost of cyclic transportation along the highway from 
to , then to with a return to is minimal. Considering that the transportation of 
ton of cargo along the highway 
costs 
rubles for km, determine
a) is it possible for a cargo of t to keep within the amount of 
thousand rubles, excluding the costs of loading and unloading cargo?
b) the same question for the amount of 60 thousand rubles taking into account the cost of a full reloading of goods (
rubles per t) at 
points out of 
? in 
points out of ? at all points?
