\tan x = \dfrac{\sin x}{\cos x}

\tan x = \dfrac{\frac{5}{13}}{\frac{12}{13}}

\tan x = \dfrac{5}{13} \times \dfrac{13}{12}

\tan x = \dfrac{5}{12}

cos x = \frac{a}{h} , so a = 12, h = 13
sinx= \frac{o}{h}, so o = 5, h = 13
tanx = \frac{o}{a}
tanx = \frac{5}{12} 

Or 

tanx =  \frac{sinx}{cosx}
tanx =  \frac{ \frac{5}{13}}{ \frac{12}{13} }
tanx = \frac{5}{12}

UkoKoshka [18]

Answer:

-x - 3y + z

Step-by-step explanation:

Think of a imaginary 1(-1 because of the sign) in front of the parenthesis and distribute it to the other number and so x will become -x, 3y will become -3y and -z will become z because two negatives make a positive.
