Question

if r¹=36,r2=18 re=12 then prove that a=30 b=24 c=18 R=15​

Answer 1

Answer:

Length of altitude through A is 24 units.

Step-by-step explanation:

From given r₁=12, r₂=18,r₃=36 we have the relation to find r as

⇒

⇒

⇒

Now, r.r₁.r₂.r₃=Δ²

⇒Δ²=6*12*18*36=46656

⇒Δ=216

Also consider, r=Δ/s

⇒

similarly, consider r₂=Δ/(s-b)

⇒

⇒area Δ=

⇒Altitude through A=
