Final answer:
Without additional information or context about the type of angles or a diagram, it is not possible to accurately determine the measures of the missing angles with only m∠3 = 54° provided.
Step-by-step explanation:
The question asks for the measure of missing angles given that m∠3 = 54°. Unfortunately, without additional context or information about the type of angles (such as adjacent angles, supplementary angles, or angles within a shape like a triangle), it is not possible to determine the measures of the missing angles. If this question is part of a larger problem involving a diagram or further specifications, please provide that information to receive an accurate answer.
Typically, one would use relationships such as complementary angles summing to 90°, supplementary angles summing to 180°, or angles in a triangle summing to 180° to find missing angles. However, the provided information alone does not offer enough details to calculate missing angles.
