Faith stands in her backyard and watches her children play. Nadia is 60 feet away in the sandbox.

Faith turns 130° and views Jolene on the swing set. Jolene is 115 feet away.

How far apart are Nadia and Jolene?

We nan use the Law of Cosines to  find the distance , D

 

D^2  = 60^2  + 115^2   -2 (60 * 115) cos ( 130)

 

D^2  = 25695

 

D  = sqrt ( 25695)  ≈  160.3 ft
