The machine part ABC is supported by a frictionless hinge at B and a 10degree wedge at C. Knowing that the coefficient of static friction is 0.20 at both surfaces of the wedge, determine (a) the force P required to move the wedge to the left (b) the component of the corresponding reaction at B. I've included a picture of the object to upload.

So far I've got the moment about C or Mc=(-Byx10) + (-120x8) => By = -96 N

and I'm lost on finding the normal force exerted on point C which is the key to the problem. : /
