The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used to find the side lanes in the longest side measures 6.2 cm?

Respuesta :

6.2=6.2+2x

I think this is the equation, but I do know that 3.1 is the measurement of the shortest angle. (6.2÷2=3.1)
