In ABC , if r₁=4, r₂=8, r₃=24 then a=

Options

  1. A0
  2. B16 5
  3. C16 5
  4. D5

Correct answer

B. 16 5

Step-by-step solution

r₁=4, r₂=8, r₃=24 we know, 1 r = 1 4 + 1 8 + 1 24 r= 12 5 We know, ^2=r r₁ r₂ r₃ = 96 5 Again, we know r= s 12 5 = 96 s 5 s=8 5 So, r₁= s-a 4= 96 5 (8 5 -a) 40- 5 a=24 a= 16 5
