Question

In the given figure, p, q and R are the points of contact. If AB =6 cm, BP=3CM, THEN the perimeter of triangle ABC is

Answer 1

Answer:

15.7082 is the perimeter of triangle abc.

Join AP .Angle APB is 90° by tangent theorem. then by using Pythagoras 6^2+3^2= 3√5 will be the answer . Then add the the sides we have got 6+3+3√5=15.7082

Answer 2

Answer:

the perimeter of triangle ABC is 18cm

Step-by-step explanation:

According to the theorem,

So, BP = BQ

=> BQ = 3cm

=> AQ = AB + BQ = (6 +3)cm = 9cm

=> AQ = AB + BP = 9cm _____ (1)

As, AQ and AR are tangents from point A

So, AQ = AR

As, CP and CR are tangents from point C.

=> AR = AQ = AC + CR

=> AR = AC + CP = 9cm _____(2)

Adding equations (1) & (2)

=> AB + BP + AC + CP = (9+9)cm

=> AB + BC + CA = 18cm

The perimeter of triangle ABC is 18cm
