Question

in the adjoining figure O and O dash are the centres of of circles radii 20 cm and 37 CM if if ab is equal to 24 cm then find the distance O and O dash​

Answer 1

Answer:

C is the mid-point of AB so that AC=12

AO

=37 and AO

2

=20 .....(Radii of circles)

Using Pythagoras theorem, we get

CO
