Hi! Given , and as three vectors, find x so that forms equal angles with the vectors and . I tried this ( is a dot product). Then I isolated and and equated them. Then I solved by x. Is this correct?

Um... not quite. The general formula: Here, the angles are equal, so we get: Equate cos theta;

From what I understood, you didn't divide by the product of the magnitudes of the vectors.
I did. I wasn't clear, my fault. Thank you very much.
Just solve for

Oh gosh, right, I don't know how I missed that part >.< Thanks for that
