The vertex is the singular of vertices and they both have angles that are measured in degrees.
56 degrees
L shape
If your "53" is in degrees, then the vertex angle is 74 degrees.
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 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.

It is 360 degrees.
