Step-by-step explanation:
let M is the mid point of AB so that, OM = x cm.
now,
AM = 8 cm
OA = 10 cm.
from triangle AMO, angle M = 90°
using Pythagoras theorem we get,
OA²= AM²+OM²
10² = 8² + x²
100 = 64 + x²
100 - 64 = x²
36 = x²
so,
x = + 6 or - 6.
here distance can not be negative so,
x = 6 cm.
I hope this will help you.
Thank you.
Happy to help.
