Q12 of 31 Page 316

If A + B = 90° and tan A = , value of cot B is

Given, A + B = 90°


And tan A =


⇒ cotB = cot(90 - A)


= tan A


=


∴ Option A is correct, the value of cot B is also


⇒ Option B is incorrect, as it does not match the given value


⇒ Option C is incorrect, as it does not match the given value


⇒ Option D is incorrect, as it does not match the given value
