Question

In the given figure AB, AC AND PQ are tangents. If ab=5cm, then find the perimeter of triangle APQ​

Answer 1

Answer:

10 cm

Step-by-step explanation:

As we know tangnets from a single point to two points of a circle are equal to each other so AB=AC,AP=AQ

Now consider the attached image;

You can infer from the above information that PD=BD

&DQ=QC .

So PB =x/2=QC

Now, AP=5-x/2=AQ

Thus,Perimeter of Triangle AQP = AQ+AP+PQ

-->(5-x/2)+(5-x/2)+ x = 10 cm
