Question

Draw a circle of diameter 7cm from a point P, 8cm away from its centre, construct a pair of

tangents to the circle​

Answer 1

Answer:

5.9 cm.

Step-by-step explanation:

Steps of construction :  

1. Draw a line segment OA=8 cm.  

2.O as centre and radius 4 cm draw a circle.  

3. Taking OA as diameter draw another circle which intersects the given circle at B and C.  

4. Join A to B and A to C.  

Result:AB and AC are required tangents.  

∴AB=AC=5.9 cm.

Answer 2

Answer:

5.9 cm

Step-by-step explanation:

step of construction:

1.Draw a line segement OA=8cm

2.O as centre and radius 4cm draw a circle.

3.Taking OA as diameter draw another circle which interests the given circle at B and C.

4.join A to B and A to C.

Result:AB and AC are required tangent.

Therefore,AB = AC=5.8cm
