What is the sum of the measurements of angles A, B, and C if angle A measures and is the same as angle B?

To find the sum of the measurements of angles A, B, and C, we need to know the value of one of the angles. You stated that angle A measures and is the same as angle B, but did not provide any specific measurement for angle A.

If we assume that angle A measures x degrees, then since angle A and angle B are equal, we can also say that angle B measures x degrees.

The sum of angles A, B, and C can be calculated by adding their measurements together:
Sum of measurements = Angle A + Angle B + Angle C

In this case, the sum of measurements would be:
Sum of measurements = x + x + Angle C

Please provide the specific measurement for angle A or any additional information to continue solving the problem.
