By definition, a Rhombus has four congruent sides which are also parallel. A Rhombus opposite angles are congruent. A Rhombus also has consecutive angles that are supplementary. Its diagonals bisect the angles too.
if you divide both the soda and the waters ounces by their price than you will get 0.15 for the soda and 0.16 for the water showing that its 1 cent more expensive than the soda
If B and C are the base angles than AB and AC are congruent so set them equal to each other to solve for x. You get x = 2. Plug the 2 into the 3x+4 to get 10
