Vectors find following in terms of x

  1. Sep 6, 2008 #1
    1. The problem statement, all variables and given/known data
    express the following in terms of x, given that m,n,o and p are each 8 m long.
    so the first diagram has x pointing upward and then m connected, pointing downward (forming roof shape) and the angle formed is 140 degrees (under the roof).
    the next one is also a roof shape but x and n are pointing in diff dirrections instead of the same way. if x is extended, i cant really make a right triangle. so im confused.

    2. Relevant equations

    3. The attempt at a solution

    fr the first one, do i just extend x to make a right triangle on m and then get 40 degrees for one of the angles. so i would get 6 for the line that was extended. is this the answer?

    I can't visualise this problem and can't understand what it is you are actually trying to express in terms of x...

    Short of drawing a diagram, do you think you've explained the problem well enough for someone here, someone who's never seen the problem before, to answer it?

    Sorry Becky I know i asked you to draw a diagram but I still can't quite get my head round this..

    You might want to repost this problem if no one replies to this post.
