Question

Pls pls solve this one:-

NUMBER 16

Answer 1

Step-by-step explanation:

tan2A=cot(A-18)

tan2A= tan{90-(A-18)

2A=90-(A-18)

2A=108-A

2A+A= 108

3A=108

A= 36

Answer 2

Answer:

Hiiiiii rita I am sandeep it is my new account ok then I said please inbox me please inbox me

Here is your answer ok

Step-by-step explanation:

Please inbox me

Answer = 36(A) ok

Now step by step

=tan 2A = cot(cota) ×(A-18)

=tan 2A = tan{90-×(A-18)}

=2a =90-(A-18)

=2a = 108-A

=2a+a= 90+18

=3a= 108

=a= 108/3

So, 108/3= 36(Answer)

I HOPE THAT'S ANSWER LIKE YOU OK

THEN PLEASE INBOX ME ME ME

INBOX ME PLEASE

I request rita please inbox me
