Answer:
Distance between the planes = 220 km (Approx)
Step-by-step explanation:
Given:
Location of first plane (a) = 110 km
Location of second plane (b) = 200 km
The angle between the plane (α) = 85°
Find:
Distance between the planes.
Computation:
[tex]Distance\ between\ the\ planes= \sqrt{a^2+b^2-2abcos\alpha} \\\\Distance\ between\ the\ planes= \sqrt{110^2+200^2-2(110)(200)cos85} \\\\Distance\ between\ the\ planes= \sqrt{12100+40,000 -3834.85268} \\\\Distance\ between\ the\ planes= \sqrt{48265.1473}\\\\Distance\ between\ the\ planes= 219.6933[/tex]
Distance between the planes = 220 km (Approx)
