Answer:
Step-by-step explanation:
Let x be the length of the shorter chord
and x+2 be the length of the longer chord
In Triangle ABC
Angles ABC =90 degrees
According to the pythagoras theorem,
(10×10) = (x×x) + (x+2)(x+2)
100 = x×x + x×x+4+4x
x=6
That is the length of the longer chord is 8cm and shorter chord is 6cm
