Answer:
4.9 cm
Step-by-step explanation:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
7*7 = x*10
49 = 10x
Divide by 10
49/10 =10x/10
4.9 =x
4.9
The intersecting chord theorem states that the product of the lengths of the line segments on each chord is equal.
10 × x = 7 × 7
10x = 49
x = 49/10
x = 4.9
