The horizontal lines are parallel and pg=qr=rs. what is xu? a)4.5 b)2.25 c)6 d)3

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

question is incomplete.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
