30=40%
x=100%

x= \frac{30*100}{40}

x= \frac{3000}{40}

x= \frac{1500}{20}

x= \frac{750}{10}

x=75

Answer:

x = 323 in

Step-by-step explanation:

Given triangles are similar, so their corresponding sides would be in proportion:

3ft = 3*12 = 36 in

5ft 8 in = 5*12 + 8 = 68 in

14 ft 3 in = 14*12 + 3 = 171 in

\frac{3 \: ft}{14 \: ft \: 3 \: in}  =  \frac{5 \: ft \: 8 \: in}{x}  \\  \\  \frac{36}{171}  =  \frac{68}{x}  \\  \\ x =  \frac{171 \times 68}{36}  \\  \\ x =   \frac{11628}{36}  \\  \\ x = 323 \: in \:  \\  \\ x = 26 ft \: 11  in
