In the accompanying diagram tangent ¯¯¯¯¯¯¯¯AB and secant ¯¯¯¯¯¯¯¯¯¯¯¯¯ACD are drawn to circle O from point A, AB = 6 and AC = 4 Find AD
We have,
AB=6,AC=4,AD=?
We know that
AB2=AC×AD
62=4×AD
AD×4=36
AD=9
Hence, this is the answer.
In the given circle, O is the centre of the circle and AD, AE are the two tangents. If BC is also a tangent, then which of the given options is true?
O is the center of circle.AB and AC are tangent drawn from A and BA perpendicular to AC. Prove that BACOis a square.
In the given figure a triangle ABC is drawn to circumscribe a circle of radius 3 cm such that the segments BD and DC into which BC is divided by the point of contact D are of length 9 cm and 3 cm respectively. Find the length of sides AB and AC.
