Question 122273
one more solution is here

since YW || XZ ...=> W have y coordinates same as Y; W(x,5)

since distance between points X an Z is {{{1+17=18}}} units, so and distance between points Y an W is {{{d=3+18=21}}} ...so {{{x=21}}}

then we have that the coordinates of W are({{{21}}},{{{5}}})
