To solve the problem, we need to find all the angles formed by the intersection of lines PQ and RS at point O, given the ratio of angles \( \angle POR \) to \( \angle ROQ \) is \( 5:7 \). ### Step-by-step Solution: 1. **Set up the angles based on the given ratio**: Let \( \angle POR = 5x \) and \( \angle ROQ = 7x \). **Hint**: Use a variable (like \( x \)) to represent the common factor in the ratio. ...
