Final answer:
Without additional context or a diagram showing the relationship between angle 4 and angle 6, it's impossible to determine the measure of angle 6 based solely on the measure of angle 4 given in the question.
Step-by-step explanation:
The student has asked what is m∠6 if m∠4 = 70°. Without additional context, such as a diagram or further description of the relationship between ∠4 and ∠6, it's impossible to provide a specific answer to this question. In mathematics, especially geometry, the measure of an angle can often be determined by the relationship it has with other angles, such as supplementary, complementary, alternate interior, or corresponding angles in the case of parallel lines cut by a transversal, or angles in geometric shapes like triangles and polygons.
For instance, if ∠4 and ∠6 are supplementary, they would add up to 180°, so m∠6 would be 180° - 70° = 110°. If they are complementary, they would add up to 90°, making m∠6 = 90° - 70° = 20°. However, without such information, one cannot determine m∠6 based solely on m∠4.
