7. If RQ = 48, QN = 26 and RN = 30 then find y when MT = 2(y + 7)

If RQ = 48, QN = 26 and RN = 30 then find y when MT = 2(y + 7) .y = 6

Step-by-step explanation:

2(y+7)=26

2y + 14 = 26

2y=12

y=6

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

good luck on ur quiz test or homework. have a good day : )
