There are a total of 180º in a triangle.
We know that one is 90º, because it's a Right Triangle, and another is 10º.
Therefore, the third must be:
180º - 90º -10º = 80º

They each measure 60 degrees
The third angle measures 18 degrees.
Each interior angle of an equilateral triangle measures 60 degrees
It is a right angle triangle and its 3rd angle is 70 degrees.
It is a right angle triangle and angle A measures 15 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle and the 3rd angle will measure 30 degrees
77 degrees
25 degrees
The third angle is 34.5 degrees
20 degrees
105
45 degrees.
If you mean an equilateral triangle then the 3rd angle is 60 degrees
They each measure 60 degrees
The missing angle measure is 100 degrees.
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
