Final answer:
Measure of angle M1 cannot be determined without additional information.
Step-by-step explanation:
To find the measure of angle M1, we need more information or context. Without any additional information, it is not possible to determine the measure of angle M1 from the options given (A) 117.5, (B) 55, (C) 110, and (D) 62.5. The measure of an angle depends on the specific triangle, polygon, or geometric shape it is a part of.
