In the given figure, TAS is a tangent to the circle, with centre O, at the point A. If ∠OBA = 32∘, find the value of x.
OB = OA (radius)
=>∠OAB = ∠OBA = 32∘
As the tangent at any point of a circle is perpendicular to the radius through the point of contact,
∠OAS = 90∘
x= ∠OAS - ∠OAB
x = 90∘ - 32∘
x = 58∘
