Question

in the figure AB = 8cm , CM = 1 cm, CM is perpendicular bisector ofAB. The radius OA =x cm. Find x

Answer 1

hope this will help you.
thank you for asking a good question.

Answer 2

Answer:

OM = OA

OA = x cm

therefore,OC = x

OM = OC - CM

OM = x - 1

x^2 = (x - 1)^2 + 4^2

x^2 = x^2 - 1 + 16

x^2 = x^2 + 17

now

2x = 17

x = 17/2

x = 8.5 cm
