Answer:

R.E.F image

Given : ∠ACB=30

∘

AB=12cm

Find :- diameter of

circle.

Solution :

We know that in a circle the measure

of central angle is twice the measure of

the inscribed angle that intercepts the same.

so ∠AOB=2∠ACB

=2×30

∘

=60

∘

Draw a line OD which is divide the angle

and AB line in equal two parts.

so ∠BOD=30

∘

& ∠ODB=90
