Secx=13/5, x lies in 4th quadrant. In 4th quadrant tan x is negative.
Sec x =hypotenuse /adjacent side.
Therefore hypotenuse =13,adjacent side =5
By pithogarous theorem, opposite side=12
Tan x=-(12/5)
Sec x =hypotenuse /adjacent side.
Therefore hypotenuse =13,adjacent side =5
By pithogarous theorem, opposite side=12
Tan x=-(12/5)
