Answer:

Step-by-step explanation:In the figure, by Pythagoras Theorem,

QR  

2

=PR  

2

−PQ  

2

 

=(13)  

2

−(12)  

2

 

=25

⇒QR=  

25

​  

=5 cm

In △PQR right angled at Q,  

QR=5 cm is side opposite to the angle P and PQ=12 cm is side adjacent to the angle P.

Therefore, tanP=  

PQ

QR

​  

=  

12

5

​  

 

Now, QR=5 cm is side adjacent to the angle R and PQ=12 cm is side opposite to the angle R.

Therefore, cotR=  

PQ

QR

​  

=  

12

​  

.

Hence, tanP−cotR=  

12
