In a triangle ABC, with usual notation, if a=12, b=16, c=20, then the ratio of the exradii of the triangle opposite to the angles in the order C, B, A is

  1. A 3: 4: 5
  2. B 6: 3: 2
  3. C 12: 7: 5
  4. D 2: 3: 5
Verified Solution

Answer & Solution

Correct Answer

(B) 6: 3: 2

Step-by-step Solution

Detailed explanation

Given, Sides of triangle a=12, b=16, c=20. s=a+b+c2=12+12+202=24 Therefore, Area of triangle =∆=ss-as-bs-c =24×12×8×4=96 Ex-radii opposite to ∠C=r3=∆s-c=964=24 Ex-radii opposite to ∠B=r2=∆s-b=968=12 Ex-radii opposite to…
