If you mean an equilateral triangle then the 3rd angle is 60 degrees

Triangles measure 180 degrees. A triangle that has one 90 degree angle is known as a right triangle.

If it's a triangle then the 3rd angle is 35 degrees

If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.

63 degrees

If the angles A, B and C forms a triangle, then angle A is 111 degrees.

The 3rd angle is: 180-92-45 = 43 degrees

The third angle measures 18 degrees.

50 degrees. 45 and 85 add up to 130 and in a triangle there are 180 degrees in total in a triangle. So subtract and you get 50 degrees.
