Please help how to solve

Answer 1

`= > in \: the \: bigger \: triangle \\ height = 14 \: ft \\ base = 22.5 \: ft \\ = > in \: smaller \: triangle \\ height = x \: ft \\ base = 9 \: ft \\ using \: ratios \\ (bigger \: height)/(smaller \: height) = (bigger \: base)/(smaller \: base) \\ (14)/(x) = (22.5)/(9) \\ (14)/(x) = 2.5 \\ x = (14)/(2.5) \\ x = 5.6 \: ft`
