Two beetles run across flat sand, starting at the same point. Beetle 1 runs 0.42 m due east, then 0.72 m at 32o north of due east. Beetle 2 also makes two runs; the first is 1.48 m at 47o east of due north. What must be the magnitude of its second run if it is to end up at the new location of beetle 1?
