In a given isosceles triangle one of the angles is 60 degrees. If one of the sides is 21 and the other is 3x. Then what is the value of x?

Respuesta :

The triangle has to be equilateral...

So, 21 = 3x
      /3       /3
        7 = x

X = 7.

But I'm not sure because the question does not make any sense.
