PA and PB are tangents to the circle and O is the centre of the circle. The radius is 5 cm and PO is 13 cm. If the area of the triangle PAB is M, then the value of `sqrt (M/15)` is :
PA और PB वृत्त के स्पर्शरेखा है और O वृत्त का केंद्र है। त्रिज्या 5 सेमी और PO =13 सेमी है। यदि त्रिभुज PAB का क्षेत्रफल M है, तो `sqrt (M/15)` का मान है:

A

a)`sqrt (24/13)`

B
