56 degrees
The vertex is the singular of vertices and they both have angles that are measured in degrees.
Vertex angle = 180 - 2(62) = 56 degrees
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.

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

20 degrees
Vertex angle = 180 - 2(62) = 56 degrees
If that '56' has units of 'degrees', then the vertex angle is 68 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.
let the vertex angle be x degrees, then the base angle is x + 9 degrees. Since in a triangle the sum of the angle is 180 degrees, and the base angles in an isosceles triangle are congruent, we have: x + 2(x + 9) = 180 x + 2x + 18 = 180 3x + 18 = 180 subtract 18 to both sides 3x = 162 divide by 3 to both sides x = 54 Thus the vertex angle is 54 degrees.
of course! anything up to 360 degrees is a regular angle. higher than 360 is a vertex angle.
If each base angle is 56°, then the vertex angle is 68°.If both base angles combined total 56°, then the vertex angle is 124°.
