Question

The main triangular sail on a sailboat is 25 feet tall and 10 feet wide at the bottom. If the sides of another sail are proportional to the main sail, and the bottom of this sail is 8 feet wide, how tall is it?

Answer 1

20 feet

Explanation:

x - the hight of another sail

`(8)/(10)=\frac x{25}\\\\x=\frac8{10}\cdot25=\frac45\cdot25=4\cdot5 = 20`
