To determine the measure of angle \( m∠4 \), I would need some information about how angles \( ∠2 \) and \( ∠4 \) are related (for example, if they are supplementary, corresponding, or alternate interior angles). Since the image is not provided, I'm unable to directly analyze their relationship.
However, if we assume common scenarios such as:
- If \( ∠2 \) and \( ∠4 \) are supplementary (add up to 180°), then \( m∠4 = 180° - m∠2 = 180° - 47° = 133° \).
- If \( ∠2 \) and \( ∠4 \) are vertical angles (equal), then \( m∠4 = m∠2 = 47° \).
- If \( ∠2 \) and \( ∠4 \) are corresponding angles when lines are crossed by a transversal, then \( m∠4 = m∠2 = 47° \).
Please provide the relationship between angles \( ∠2 \) and \( ∠4 \) or describe the scenario, and I can give a definitive answer.
