Hope it helps!! Mark this answer as brainliest if u found it useful..

Step-by-step explanation:

tan A = 5/12 = Opposite side/ adjacent side  

Assume a right angled triangle.  Find the hypotenuse using the pythagoras theorem. Hypotenuse = √(144+25) = √169 = 13

Sin A = Opposite side / Hypotenuse = 5/13  

Cosec A = 1/sin A =13/5

Cos A  = Adjacent side / Hypotenuse  = 12/13

sec A = 1/ cos A = 13/12

Cot A = 1/tan A =12/5

 

Answer 2

Answer:

sin A =5

cos A =12

cosec A=1/5

sec A=1/12

cot A=12/5
