If `(sinx)/a=(cosx)/b=(tanx)/c=k ,` then `b c+1/(c k)+(a k)/(1+b k)` is equal to `k(a+1/a)` (b) `1//k(a+1/a)` `1/(k^2)` (d) `a/k`

If (sinx)/a=(cosx)/b=(tanx)/c=k , then b c+1/(c k)+(a k)/(1+b k) is equal to (a) k(a+1/a) (b) 1//k(a+1/a) 1/(k^2) (d) a/k

If (sinx)/(a) = (cosx)/(b) = (tanx)/(c ) = k , then bc + (1)/(ck) + (ak)/(1+bk) is equal to

If (sin x)/(a)=(cos x)/(b_(k))=(tan x)/(c)=k, then bc+(1)/(ck)+(ak)/(1+bk) is equal to k(a+(1)/(a)) (b) 1/k(a+(1)/(a))(1)/(k^(2))(d)(a)/(k)

If sinx/a=cosx/b=tanx/c=k and bc+1/(ck)+(ak)/(1+bk)=?

If (a+b)/(c)=(b+c)/(a)=(c+a)/(b)=k, then k is equal to 0 b.1 c.2 d.a+b+c

If x=log_(k)b=log_(b)c=(1)/(2)log_(c)d, then log_(k)d is equal to
