Question

tan 5=Cot (90-A)= what will be the answer

Answer 1

Hi ,

******************************

cot( 90 - A ) = tanA
*******************************

Now ,

tan 5 = cot ( 90 - A )

tan 5 = tan A

5 = A

Therefore ,

A = 5

I hope this helps you.

Answer 2

Hey

+_+ Wish to know what's truly yours in the answer ? ( :p The Answer )


$\cot( {90}^{o} - \alpha ) = \tan( \alpha ) = \tan(5)$

$= > \alpha = n({180}^{o} ) + {5}^{o} \: \forall \: n =integer$

Hence, A = n( 180° ) + 5° for all integral value of n
