A triangular distributed load of max intensity $w=600\frac{N}{m}$ acts on beam $AB.$ The beam is supported by a pin at A and member $CD,$ which is connected by pins at $C$ and $D.$ Determine the reaction forces at A and $C.$ Enter your answers in Cartesian components. Assume the weights of both beam $AB$ and member $CD$ are negligible $($as almost always, in this class$).$

Values for dimensions on the figure are given in the following table. Note the figure may not be to scale.
