Question

sin A =5/4 cosecA/1+Cot​

Answer 1

☆ Given :

Sin A = 5/4

☆ To find :

Cosec A / 1 + Cot A = ?

☆ Solution :

sin range = [ -1 , 1 ]

Sin A = 5 /4 ----> which is not in the range.

Hence Sin A is not possible !!!

The correct question is Sin A = 4/5

Then by pythagoras theorem ,

we found that cosec A = 1 / sin A = 5 /4

cot A = Adj / opp = 3 / 4

By substituting The answer is 5/7
