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
Let the second angle be x degrees. The first angle would then be x + 24 degrees, and the third angle would be 4x degrees. According to the triangle angle sum theorem, the sum of all three angles in a triangle is 180 degrees. Therefore, you can set up the equation x + (x + 24) + 4x = 180 and solve for x to find the measures of all three angles.
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
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
it depends on the triangle
If two angles of a triangle each measure 55 what is the measure of the third angle?
