Any measure you like. The shape has not been specified properly.

The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.

Vertex angle = 180 - 2(62) = 56 degrees

Vertex angle is 180-53-53 = 74 degrees

You require another piece of information. Knowing the "vertex" angle will not tell you the length of any one side. You can have a triangle the size of the continental USA with a "vertex" angle of 15 degrees and you can have a triangle invisible to the human eye with a "vertex" angle of 15 degrees. You can see how these would have different side lengths.

Vertex angle = 180 - 2(62) = 56 degrees

If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
