Question

Find the lengrh of OB given if AB is 8cm and OC is 3cm ​

Answer 1

Answer:

As we know that OC is perpendicular bisector of AB so AB = 8cm then AC and BC will be 4cm.

Step-by-step explanation:

Then use Pythagoras theorem to Find OB

Given :- OC = 3cm and BC = 4cm

${ob}^{2} = {oc}^{2} + {bc}^{2}$

$now \: put \: the \: values$

${ob}^{2} = {3}^{2} + {4}^{2} \\ {ob}^{2} = 9 + 16 \\ {ob}^{2} = 25$

OB = √25

OB = 5cm

Hence we found the OB.
