Question

calculate the length marked by X in this diagram the unit of length being cm. ( o is the centre in this diagram) ​

Answer 1

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.

Answer 2

Answer:

6 cm

Step-by-step explanation:

$\sqrt{10 ^{2} - 8 ^{2} } = 6$
