Answer 1

Step-by-step explanation:

Angle AOB=2 angle ACB

=>Angle AOB=2*48° ( Angle at the centre of the circle is twice the angle made by the tangent)

=>Angle AOB=96°

In triangle AOB,

Angle OAB = Angle OBA ( OA=OB and angles opposite equal sides are equal)

Taking angle OAB= Angle OBA=x

x+x+96°=180° ( sum of the all the angles of a triangle is 180°)

=> 2x+96=180

=> 2x= 180-96

=> 2x= 84

=> x= 84/2

=> x= 42°

Angle OAB=42°
