Quadrilateral wxyz is on a coordinate plane. segment yz is on the line x+y=7, and segment xw is on the line x+y=3. which statement proves how segments yz and wx are related

x+y=7

y = -x + 7

x+y=3

y = -x + 3

these both have slope -1 so are parallel.   that's the

answer: last choice

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
