The perpendicular disector of a chord xy, cut xy at n and the circle at P. If xy = 16cm and NP = 2cm calculate the radius of the circle

17

Step-by-step explanation:

If the centre of the circle is  O , then  △OXN  is a right triangle. We also know that,

XN=16/2=8  

ON=r−2  ( r  is the radius of the circle)

OX=r  

XN2+ON2=OX2  

82+(r−2)2=r2  

Solving the above equation will give us

4r=68  

r=17

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
