Answer 1

Answer is x=7

Explanation:

`given \: that \: triangle \: stu \: is \: \\ similarto \: triangle \: plm \\ by \: similarity \: theorem \\ (st)/(pl) = (tu)/(lm) = (su)/(pm) \\ (x + 1)/(72) = (2x - 3)/(99) \\ cancelling \: by \: 9 \: which \: is \: common \\ (x + 1)/(8) = (2x - 3)/(11) \\ 11(x + 1) = 8(2x - 3) \\ 11x + 11 = 16x - 24 \\ 11 + 24 = 16x - 11x \\ 35 = 5x \\ therefore \: x = 7`

HAVE A NICE DAY!
