VWXY is a parallelogram. Find the measure of XY and WY 8

VWXY Is A Parallelogram Find The Measure Of XY And WY 8 class=

Sagot :

Remember that

in a parallelogram, the diagonals bisect each other

that means

VZ=ZX

substitute given values

n+7=3n

solve for n

3n-n=7

2n=7

n=3.5

therefore

VX=(n+7)+3n ----> by addition segments postulate

VX=4n+7

substitute the value of n

VX=4(3.5)+7

VX=21
