Question

If tan2A=cot (A-21) degree where to a is an acute angle then find the value of A

Answer 1

Answer:37

Step-by-step explanation:Hey !

★ Here is your answer ★

Tan 2A = Cot ( A - 21 )

=> Cot ( 90- 2A ) = Cot ( A - 21 )

=> 90 - 2A = A - 21

=> 3A = 111

=> A = 111/3

=> A = 37°

Hence,

A = 37°

Answer 2

=>$\huge\boxed{\texttt{\fcolorbox{red}{white}{hello}}}$

=>tan2A=cot (A-21)°

=> Cot ( 90- 2A ) = Cot ( A - 21 )

=> 90 - 2A = A - 21

=> 3A = 111

=> A = 111/3

hence,

=>$\huge\boxed{\texttt{\fcolorbox{red}{white}{A=37°}}}$
