Final answer:
Without adequate information or context, the lengths of segments ST and TU cannot be determined, thus the answer is (c) Unable to determine from the information provided.
Step-by-step explanation:
The question provided does not include enough information to determine the lengths of segments ST and TU. Generally, to solve for the lengths of segments in mathematics, one would need specific numerical information about the segments or related geometric properties. This could include known lengths of other segments, angles, coordinates, or algebraic expressions that relate to ST and TU. Without such data or additional context, such as a diagram or equation, it is impossible to calculate these lengths; therefore, the answer is (c) Unable to determine from the information provided. If any additional information or relevant context is given, then a more precise answer could be provided.
