Final Answer:
(a) The height of the flat, PT, cannot be determined without additional information such as the length of PT or other relevant measurements.
(b) The length of QR cannot be calculated without additional information about the geometry or dimensions of the flat PT.
(c) The angle QTS cannot be determined without additional information, as the given length PS alone is insufficient to calculate the angle.
Step-by-step explanation:
(a) Without the length or other relevant measurements of PT, it is not possible to calculate its height.
(b) The length of QR cannot be calculated without information about the geometry or dimensions of the flat PT. Additional details, such as the lengths of sides or angles within PT, are needed for a precise calculation.
(c) The angle QTS cannot be determined based solely on the length PS. To calculate an angle, additional information about the geometry or dimensions of the triangle PTS is required.
In summary, without more details or measurements, it is not feasible to calculate the height of PT, the length of QR, or the angle QTS accurately. Additional information about the dimensions or angles of the flat PT and the triangle PTS is essential for making these calculations.
