Mathematics

Determine the value of x in the figure given below.

$60^{\circ}$

SOLUTION
O is the centre of the circle and OA and OB and OC are the radius of the circle..
Thus, $OA=OB=OC$
$∠OAB= ∠OBA(∵OA=OB)$
$=>∠OAB=35^∘$
Similarly, $∠OAC=\angle OCA$
$=>\angle OAC=25^∘$
Now,
$\angle BAC=\angle OAB+\angle OAC$
$∴ ∠x=35^∘+25^∘=60^∘$
