Structural Integrity of a Triangular Support Brace

An engineer is inspecting a triangular support brace for a new building. To ensure the brace fits the design specifications, the engineer needs to verify the measure of the third interior angle. They have already measured two of the angles as 45° and 75°. Based on the standard geometry problem-solving strategy, identify the constant total sum (in degrees) that the engineer must use for all three interior angles to set up their equation.
