180 degrees

180
180- total of the first two angles= 3rd angle
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.
If two angles of a triangle each measure 55 what is the measure of the third angle?
The internal angles of a triangle always total 180º. So 180º - (15º + 85º) = 80º.
100.
The total number of degrees in a triangle is 180. this will not change no matter what type of triangle it is. (obtuse, acute, right angle, etc)
180 degrees.
180- total of the first two angles= 3rd angle
Any three numbers that total 180
In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95
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.
The total sum of all angles in any triangle is 180 degrees.
Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
angle with the greatest measure
it depends on the triangle
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
If two angles of a triangle each measure 55 what is the measure of the third angle?
