Question

If OA= 10 cm, AB= 12cm and OD is perpendicular to AN, then find CD.

Answer 1

Answer:

Hey guy here is your answer

Answer 2

Answer:

2 cm

Step-by-step explanation:

In triangle OAC

OA = 10 cm (Given)

AC = 6 cm ( OD bisects AB)

By pythogoras theorem

OA²=AC²+OC²

10²=6²+OC²

100-36=OC²

64=OC²

8cm=OC

OD=10 cm (Radii)

CD=OD-OC

CD=10-8

CD=2cm
