IND ABC, AR-3cm, AC=9cm thenfind A(TRIANGLE ABR) :A(TRIANGLE ABC) |
|
Answer» Answer: In the given figure, ΔABC CIRCUMSCRIBED the circle with centre O. Radius OD=3cm BD=6cm,DC=9cm Area of ΔABC=54cm2 To find : LENGTH of AB and AC. AF and EA are tangents to the circle at point A. Let AF=EA=x BD and BF are tangents to the circle at point B. BD=BF=6cm CD and CE are tangents to the circle at point C. CD=CE=9cm Now, NEW sides of the triangle are: AB=AF+FB=x+6cm AC=AE+EC=x+9cm BC=BD+DC=6+9=15cm Now, using Heron's formula: Area of triangle ABC=s(s−a)(s−b)(s−c) Where S=2a+b+c S=1/2(x+6+x+9+15)=x+15 Area of ABC=(x+15)(x+15−(x+6))(x+15−(x−9))(x+15−15) Or 54=(x+15)(9)(6)(x) SQUARING both sides, we have Step-by-step explanation: hopes its helps |
