Let distance between two cities = x
Let C₂ = distance from farther city from the sight at 30 degrees
Let C₁ = distance from nearer city from the sight at 45 degrees
Height from the ground to air balloon = 750 m
Distance from below the balloon to the farther city (C₂):
tan 30⁰ = [tex] \frac{750}{C _{2} } [/tex]
C₂ = [tex] \frac{750}{tan30} [/tex]
C₂ = [tex] \frac{750}{0.58} [/tex]
C₂ = 1,293 m
Distance from below the balloon to nearer city (C₁):
tan 45 = [tex] \frac{750}{C _{1} } [/tex]
C₁ = [tex] \frac{750}{tan45} [/tex]
C₁ = [tex] \frac{750}{1} [/tex]
C₁ = 750 m
Distance (x)between two cities:
x = C₂ - C₁
x = 1,293 m - 750 m
x = 543 m
ANSWER: The distance between two cities are 543 meters.
