Answer:

B. QT = 18; TR = 8

Explanation:

QT = x + 6

SR = 12

PS = 27

TR = x - 4

PR/SR = QR/TR (Similarity theorem)

PR = PS + SR = 27 + 12

PR = 39

QR = QT + TR = x + 6 + x - 4

QR = 2x + 2

Substitute

39/12 = (2x + 2)/(x - 4)

13/4 = (2x + 2)/(x - 4)

Cross multiply

13(x - 4) = 4(2x + 2)

13x - 52 = 8x + 8

Collect like terms

13x - 8x = 52 + 8

5x = 60

x = 60/5

x = 12

✔️QT = x + 6

Plug in the value of x

QT = 12 + 6

QT = 18

✔️TR = x - 4 = 12 - 4

TR = 8
