PQRS is a cyclic quadrilateral in which PQ = x cm, QR= 16.8 cm, RS = 14 cm, PS = 25.2 cm, and PR bisects QS. What is the value of x ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e 21
Explanation:
By the property,
PQ × QR = RS × PS
⇒ x × 16.8 = 14 × 25.2
⇒ x = 352.8/16.8 = 21 cm
