The image you provided shows a question about a rectangle, PQRS, with the length ST given as 9 units and the measure of angle ∠PRS as 25°. The problem asks to find various measurements, including the lengths of certain sides and angles.

Let's break down the solution step by step:

1. Given Information:

   • PQRS is a rectangle, so opposite sides are equal and all angles are right angles (90°).
   • ST = 9 units.
   • ∠PRS = 25°.

2. a) SQ:
   Since PQRS is a rectangle, we know that the length of one side will equal the other. To find SQ, we need additional information such as using trigonometry or other properties of the rectangle.

3. b) PR:
   We may apply trigonometry here. Since ∠PRS = 25°, we can potentially use the sine or cosine functions to find PR in the right triangle formed by points P, Q, and R.

4. c) ∠QPR:
   This angle is likely complementary to ∠PRS since the sum of the angles in a right triangle equals 90°. If ∠PRS = 25°, then ∠QPR = 90° - 25°.

5. d) ∠PSR:
   As this is a rectangle, ∠PSR is a right angle, i.e., 90°.
