60 degrees for an equilateral triangle but it depends on other types! Other angle measure could be 30, 45, or 90 degrees as well.
60 degrees and it is an equilateral triangle.

63 degrees because 180 -39 -78 = 63
A right angle is formed when two lines meet at an angle whose measure is 90 degrees. A right triangle is a triangle in which one angle is a right angle. (Note: there cannot be more than one.)
55°
no it does not
80 degrees
50 degrees
77. The sum of the three angles in a triangle equal the sum of 180 degrees

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.
