Components of vectors

  1. Feb 13, 2005 #1
    A commuter airplane starts from an airport located at the origin. first it flies to city "A" located a =110km away from the airport in a direction alpha = 36 degrees North of East. Next it flies b =61.8km beta=38 degrees west of north to city "B". Finally it flies c=168 km due West to city "C". Consider "E" to be the positive x and "N" to be the positive y axis. Which of the following is equal to the x-component bx of vector B? then the answers are like bx=-btanbeta and so forth

    ok i got bx=-b sin beta, and by = b cos beta, but for the rx compent im not getting the right answer i think its ax + bx=rx -110sin(36)+61.8sin(38) but that wasnt right
