Final answer:
To determine the measure of Angle 3 with lines h and j being parallel, additional information or the diagram is needed as angle relationships depend on the position of the angles formed by a transversal intersecting parallel lines.
Step-by-step explanation:
It appears that there is some confusion in the details provided in the student's question regarding the measure of Angle 3. To accurately answer this question, additional information about the diagram and the relationships between the angles would be necessary. Usually, parallel lines and the angles they form with a transversal follow certain angle relationships like corresponding angles, alternate interior angles, and consecutive interior angles, which are equal or supplementary in case of parallel lines intersected by a transversal. However, since the specific details about the angles in the diagram are missing or the diagram is not provided, we cannot determine the measure of Angle 3. More information is needed to solve this problem correctly.
