63 degrees because 180 -39 -78 = 63
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°.

Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
Since you know one base angle is 54 then the other base angle is also 54 making a total of 108. Since a triangle is 180, your vertex angle is 72.
45 degrees.
