Let L denote a blimp, A and B - cars. Then LR=2460 feet , φ1=26.5°,φ2=34.9°. The goal is to find distance AB=AR+RB.
From the triangle ALR : AR=LR⋅tan(90°−φ1)≈2460⋅2=4920
From the triangle BLR : RB=LR⋅tan(90°−φ2)≈2460⋅1.43≈3526.3
Finaly, AB=AR+RB=4920+3526.3≈8446.3≈8446.
Answer: The parked cars are 8446 feet apart.
