Final answer:
Without additional context or clarification, the provided information does not contain the specific angle measurements of 105°, 30°, and 45° requested in the question. Therefore, it is not possible to accurately match the lettered items with the numbered items.
Step-by-step explanation:
To match the angle with its measure, we need to consider the given information:
- (a) corresponds to 30.1°
- (b) corresponds to 48.7°
- (c) is a simple 'No' and doesn't correspond to a degree measurement
- (d) specifies an equation process that results in an angle of approximately 31.1°
The challenge and practice problems contain various angle measurements or calculations, such as 88.6°, 9.04°, or the angle between clock hands at a certain time. However, none of these directly match the lettered items 'a', 'b', or 'c' from the original question, which are specifically 105°, 30°, and 45°, respectively.
Therefore, there is not enough information provided to accurately match the lettered items with the listed angles '1.', '2.', and '3.'. Additional context or clarification is needed to determine the correct angle measurements in connection to 'angle 1', 'angle 2', and 'angle 3'.
