Two vectors have magnitudes of 10 and 15

  1. Apr 1, 2007 #1
    Hey i'm just having trouble with this question

    Two vectors have magnitudes of 10 and 15. The angle between them when they are drawn with their tails at the same point is 65 deg. The component of the longer vector along the line perpendicular to the shorter vector, in the plane of the vectors, is:

    a)0
    b)4.2
    c)9.1
    d)13.6
    e)6.3

    Thanks Nath

    In fact, I am moving this to the homework forum.

    Draw a picture of the situation. Do you see a right triangle? What trig function will help you find the length you want?
