In the figure, AQ, AR and BC are tangents to circle with centre O, if AB = 7 cm, BC = 5 cm, AC = 5 cm, then length of the tangent AQ is:
5 cm
7 cm
17 cm
8.5 cm
In the given figure, AP, AQ and BC are tangents to the circle. If AB = 5 cm, AC = 6 cm and BC = 4 cm then the length of AP is
(a) 15 cm (b) 10 cm (c) 9 cm (d) 7.5 cm
If ΔABC≅ΔDEF, AB = 5 cm, BC = 6 cm, AC = 7 cm, then the length of EF is:
In the figure, the pair of tangents AP and AQ drawn form an external point A to a circle with centre O are perpendicular to each other and length of each tangent is 5 cm. Then the radius of the circle is:
The sides of a quadrilateral ABCD are tangents to the circle with centre ‘O’. If AB = 8 cm and CD = 5 cm find AD + BC.
