Final answer:
The question asks for the measures of m21 and m22 but does not provide sufficient context or information to answer accurately. An understanding of what these measures refer to is necessary to provide a correct answer.
Step-by-step explanation:
The question provided is asking for the measures of m21 and m22. The reference to 'measures' and notated with 'm' followed by numbers suggests this might be related to angles, sequences, or some form of coded mathematical values. However, without clear context or a specified diagram or sequence, it's impossible to determine what m21 and m22 represent and therefore not feasible to give an accurate answer to the provided options A through D. The problem may be from a specific textbook or classwork that provides the necessary context to answer accurately.
In mathematics, especially when dealing with measures, context is crucial to determine what is being measured and how. Measures could refer to angles in geometry, terms in a sequence, or other mathematical values depending on the topic studied. The information provided does not give enough context to identify what these measures refer to or how they should be calculated or interpreted.
