Question

the radius of a circle is 13 cm and lengths of one of its cord is 10cm. the distance​

Answer 1

Answer:

12 cm

Step-by-step explanation:

when we join the ends of the chord with centre a triangle is formed with sides 10 ,13 ,13 i.e chord (10cm) as base and radius (13cm) as others two sides , now draw a line from centre to midpoint of the chord , it forms a right angled triangle with radius (13cm) as hypotenuse and base (5cm) and assume remaining as x

now pythogorian therom

13×13=(5×5) + (x×x)

169=25 +(x×x)

(x×x) = 169-25

x=12cm
