 \frac{ \tan(50) +  \sec(50)  }{ \cot(40) +  \csc(40)  }  +  \cos(40)  \csc(50)  \\  =   \frac{ \cot(90 - 50)  +  \ \csc (90 - 50) }{ \cot(40)  +  \csc(40) }  +  \cos(40)  \sec(90 - 50)  \\  = 1 +  \frac{ \cos(40) }{ \cos(40) }  \\  = 1 + 1 = 2
Brainliest please!!

littledora: plz...can u explain me this answer I am not understanding
shanujindal48p68s3s: We know that sin x= cos (90-x) and tan x = cot (90-x) and sec x = cosec(90-x) and vice versa
littledora: ok
shanujindal48p68s3s: Brainliest?
