In triangle ABC, find k if there is only one possible value for x.
|dw:1352018124446:dw| the only possible solution is when the segment of length k is perpendicular to the segment of length x.
Thanks sirm3d. Hmm... sort of
I don't quite understand why the only possible solution is when the segment of length k is perpendicular to the segment of length x
If k is not perpendicular, you will have 2 different values of x. Look at the picture sirm3d drew for you.
But in the statement of the problem you have only one possible value for x.
Oh I see now! Thanks for that :)
