Let the distance between two tall buildings be x,

In Rt△ACE,

AE=CEtan37, that is, AE=x? tan37

Similarly, in Rt△DBF,

BF=x？ tan48，

∫AE+BF+EF = 30×2.8，EF= 10

∴AE+BF=74, which is x? tan37 +x？ Tan48 =74, that is, x (34+1110) = 74,

X=40 meters.

The distance between the two tall buildings is 40 meters.
