L shape
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.

If your "53" is in degrees, then the vertex angle is 74 degrees.

Vertex angle = 180 - 2(62) = 56 degrees
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.

60 degrees.
80 degrees
If the 58°-angle is one of the base angles, then the vertex angle is 64°.If the 58°-angle is the vertex angle, then the vertex angle is 58°.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
The third angle of what shape?
