Question

please answer this ..

Answer 1

\[2tanA=(1-\tan^2A)\cot56\]

Answer 2

hey theres a formula

tan2A= 2tanA/1-tan^2A

hence tan2A=cot56

tan2A.tan56=1

we also have another that if tanAtanB=1
then A+B=90

hence

2A+56=90

2A=90-56

A=34/2

=17 i hope its correct

Answer 3

aww.. it's correct!! thanks for the solution
