Question

. Tan 5°. tan 40° tan 45° tan 50° tan 85° is equal to​

Answer 1

Answer:

tan5 tan40 tan45 tan50 tan85

=> tan5 * tan40 * 1 * tan(90-40) * tan(90-5)

=>tan5 * tan40 * cot40 * cot5

=> (tan5*cot5) * (tan40*cot40)

=1*1

=1

Answer 2

Answer:

covert them see

tan5 = cot 85

tan40 =cot 50

and also tan50* cot 50 =1

tan85* cot 85 =1

so

1 * tan45

now tan 45 is 1

therefore

1*1 = 1

hence
