Quadrilateral ABCD circumscribes a circle. If AB = 8 cm, BC = 7 cm and CD = 6 cm, then the length of AD is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 7 cm
AB = 8 cm, BC = 7 cm, CD = 6 cm
Since, Quadrilateral ABCD circumscribes circle:
So,
AB + CD = BC + AD
⇒ 8 + 6 = 7 + AC
⇒ AC = 14 - 7 = 7 cm
