Final answer:
The correct order of angles from smallest to largest among the given options is (d) 30°, 60°, 120°, which places the angles in ascending order.
Step-by-step explanation:
The question is asking to arrange given angles in order from the smallest to the largest. The options provided include different sets of angles, and we need to identify the one that presents these angles in ascending order.
- (a) 45°, 90°, 135°
- (b) 180°, 90°, 45°
- (c) 60°, 120°, 90°
- (d) 30°, 60°, 120°
Looking at the above options, we can see that option (d) 30°, 60°, 120° shows the angles listed from the smallest to the largest. Therefore, the correct answer is option (d).
