Answer:
x = 32°
Explanation:
To find:-
Answer:-
As we know that angle made by tangent on the centre is a right angle . So here
OBC will be 90° ( as CB is tangent on the circle.) Again we know that the angles opposite to equal sides are equal . Therefore here OB and OA are radii of the circle which are equal. So we can say that;

Again we know that the angle sum property of a triangle is 180° . Therefore in ∆OBA ,




Finally look into the ∆OBC ,





Hence the value of x is 32°.
