Answer:

Step-by-step explanation:

Let O be the center of the circle of radius 10 cm .A cord AB=2.x cm long is 5 cm

away from the center . Draw a perpendicular OD on AB.

In right angled triangle ODB

OD^2+DB^2 = OB^2

5^2+x^2=10^2

or. x^2=100–25=75

or. x= 5√3

Therefore answer is equal to

17.32cm
