Bonnie had previously calculated the cross product of two vectors in R, but unfortunately sprayed part of their work with tea. Their calculation now looks like: -26) x2 x -6 = 15 x3 -5 8 a) Bonnie realises they can rewrite the expression above as a matrix equation X1 -26 A x) 15 for some appropriate matrix 8. x3 A. Find A. A = b) Find a possible value for x1 x) given Bonnie remembers that its length is X3. V21 X1 x2 %3D X3 c) Explain geometrically why there are two different possible answers to the previous part.
