Correct Answer
Option C
Explanation
To determine the value of \( (7y + 5) \) in the given parallelogram \( PQRS \), we need to use the properties of parallelograms and the information provided about the diagonals. In a parallelogram, the diagonals bisect each other. This means that: \[ OP = OR \] \[ OQ = OS \] Given: - \( OP = (x + 7) \) cm - \( OR = 20 \) cm…Read More
