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°.
The sum of one angle is simply the measure of that angle.
63 degrees because 180 -39 -78 = 63
Each interior angle is 157.5
Interior angle: 144 degrees
55°

135
80 degrees
63 degrees because 180 -39 -78 = 63
1st angle = 30 degrees 2nd angle = 60 degrees
Each interior angle is 157.5
Each interior angle measures: 152o 18' 27.69''
If by one angle you mean the interior angle that would be 108. If you mean the central angle thats 72.
A right angle is one of 90 degrees. An acute angle of 30 degrees would be one third of that.
