1. The problem asks to find the length of the shortest side of the triangle in millimetres and the size of the largest angle. 2. Since the largest angle is given as 124°, the shortest side is opposite this largest angle in a scalene triangle. 3. Without specific side lengths or a scale, we cannot numerically measure the shortest side from the image alone. 4. However, the largest angle is already provided as 124°. 5. Therefore, the answer to part (b) is 124°. 6. For part (a), if no scale or side lengths are given, the shortest side length cannot be determined numerically. Answer: a) Cannot determine the shortest side length without scale or measurements. b) Largest angle = 124°.
