Question

07. tan 18° + tan 27° + tan 18° tan 27​

Answer 1

Let us add 18 and 27 to get 45.

Let us add 18 and 27 to get 45.So tan(18+27) = 1 = tan 18 + tan 27/[1 - tan 18.tan 27] or

Let us add 18 and 27 to get 45.So tan(18+27) = 1 = tan 18 + tan 27/[1 - tan 18.tan 27] ortan 18 + tan 27 = 1 - tan 18.tan 27, or

Let us add 18 and 27 to get 45.So tan(18+27) = 1 = tan 18 + tan 27/[1 - tan 18.tan 27] ortan 18 + tan 27 = 1 - tan 18.tan 27, ortan 18 + tan 27 + tan 18.tan 27 = 1.

Let us add 18 and 27 to get 45.So tan(18+27) = 1 = tan 18 + tan 27/[1 - tan 18.tan 27] ortan 18 + tan 27 = 1 - tan 18.tan 27, ortan 18 + tan 27 + tan 18.tan 27 = 1.Hence the answer is 1.✔️✔️
