Decide whether the triangles are similar. if so, determine the appropriate expression to solve for x. triangles abc and edf, where triangle abc has angle a measuring 47 degrees, angle c measuring 62 degrees, side ac labeled as y, side ab labeled as w, and side bc labeled as x and triangle edf has angle d measuring 71 degrees, angle e measuring 47 degrees, side de labeled z, side ef labeled u, and side df labeled r the triangles are not similar; no expression for x can be found. δabc ~ δdef; x equals r times w over u δabc ~ δedf; x equals r times w over u δabc ~ δedf; x equals r times w over z
