(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You are given vectors vec A= 4.6i - 6.6j and vec B= - 3.0i + 7.2j. A third vector vec C lies in the xy-plane. Vector vec C is perpendicular to vector vec A and the scalar product of vec C with vec B is 18.0. (the i and j are hat values, they have a ^ over them)

2. Relevant equations

C * B = 18

C * B = |C|*|B|cos(x)

A * C = 0, because they are parallel

3. The attempt at a solution

I used the two equations

(Cx)(Bx)+(Cy)(By) = 18

(Ax)(Cx)+(Ay)(Cy) = 0

but could not reach a solution. I would greatly appreciate some guidance
