Consider the following statementsx = ~-y; w = x = y = z; q = a?b:c?d:e?f:g;

answer: x=60

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
