63 degrees because 180 -39 -78 = 63
If they are the angles of a triangle then the missing angle is 116 degrees
180-39-77 = 64 degrees
Suppose the angle is x, Then its supplementary is 180-x So x+39 = 2(180-x) = 360-2x Then 3x = 399 So x = 133 and 180-x = 47
Each exterior angle: 90 13' 50.77'' Each interior angle: 1700 46' 9.23''

What kind of angel is 180°
The answer depends on which angle is 39 degrees.
63 degrees because 180 -39 -78 = 63
If they are the angles of a triangle then the missing angle is 116 degrees
180-39-77 = 64 degrees
Suppose the angle is x, Then its supplementary is 180-x So x+39 = 2(180-x) = 360-2x Then 3x = 399 So x = 133 and 180-x = 47
39
90-39 = 51 degrees
9.3
Each exterior angle: 90 13' 50.77'' Each interior angle: 1700 46' 9.23''
98 + 43 + 39 = 180 degreesTherefore the third angle is 39, as all angles must add up to 180 degrees.
