Question

tan A=1/root 3 cot B =1/root3 find A+B​

Answer 1

Tan a is 1 by root 3But we know only tank 30 as 1 by root 3 as value

so the value of a is 30.

Similarly, ur asking what is value of b when cot b equals root 1 by root 3. So here we reciprocal both sides, which would be Tan B equals root 3 and we know only tan 60 equal root 3 so value of a is 60.

And thus value of a plus b equal thirty plus sixty which is ninety.
