A circle of radius 4 cm is drawn inscribed in a right angle triangle ABC, right angled at C. If AC=12 cm, then the value of CB is:

​The radius of the inscribed circle = 4 cm.

AC = 12 cm (one of the legs of the right-angled triangle).

The triangle is right-angled at C.

Concept Used: ​

Properties of tangent: 

Tangents drawn to the circle from an external point has equal length.

Pythagoras theorem: 

​$$\text{(Hypotenuse)}^2 =\text{(Base)}^2 + \text{(Perpendicular)}^2$$
