RHS
.
(s-c)²c²/(s+c)²s² = x²
.
x= (q-p)q/(p+q)p
.
x= (q²-qp)/(p²+pq)

Isme equal angle kaise possible h,wo 25 m ko whi angle se dekhta h or 5 m wale ko v who angle se

@imgroooot ise krna to short me long jaa rha mera

a-b = (c-b)/bc
b-c = (c-a)/ca
a-c = (b-a)/bc
.
multiply...
.
(abc)² = 1
.
abc = ±1

Ye btana koi

Square both sides
.
(S-c)²/(s+c)² add 1
.
sec²θ = 2/(s+c)²
.
(s+c) = ±√2cosθ
