In parallelogram WXYZ, what is CY?
CY=___ ft
2 answers:
<span>The correct answer is 11 ft. Explanation : The diagonals of a parallelogram bisect each other. This means that the portion marked x+4 is the same length as the portion marked 2x-7; this gives us the equation x+4=2x-7. Subtract x from each side: x+4-x=2x-7-x 4=x-7. Add 7 to both sides: 4+7=x-7+7 11=x</span>
You forgot to put the 11 into the equation for CY: 2(11) - 7 = 15
