Answer:

-5

Step-by-step explanation:

Cos = Base/ Hypotenuse = 5/13

By using pythagors theorem,

 {H}^{2}  =  {P }^{2}  +  { B}^{2}

 {13}^{2}  =  {5}^{2}  +  {P}^{2}

169 - 25 =  {P}^{2}

 \sqrt{144 }  = 12 \: cm

We know that,

Tan = Perpendicular/Base = 12/5

Sec = Hypotenuse/Base = 13/5

 { \tan}^{2}  -  {  \sec}^{2}

( { \frac{12}{5} })^{2}  - ( { \frac{13}{5} )}^{2}

 \frac{144}{25}  -  \frac{169}{25}

 \frac{ - 25}{5}  =  - 5
