Question

You are camping with two friends, Joe and Karl. Since all three of you like your privacy, you don't pitch your tents close together. Joe's tent is 15.0 from yours, in the direction 26.0 north of east. Karl's tent is 26.5 from yours, in the direction 36.5 south of east. what is the distance between K and J?

Answer 1

Using the law of cosines

JK^2 = 15^2 + 26.5^2 - 2(15)(26.5)cos(26°+36.5°)
= 225 + 702.25 - 354.73
= 572.52
JK = 23.93

Answer 2
