Final answer:
The problem does not provide enough information to determine the length of RT. You would need to know the length of TW or have another relationship between RT and TW to solve for RT.
Step-by-step explanation:
The question RT\TW = 1/2 asks for the length of RT. However, this formula does not provide enough information to solve for RT without knowing either TW or another relationship between RT and TW. In typical algebraic problems like this, you would need both portions of a ratio to find the length of one part. For instance, if TW was given to be a specific length, you could multiply that length by 1/2 to obtain the length of RT.
Without additional information about the lengths of RT or TW or the context of the problem, it is not possible to determine the length of RT with certainty.
