Question

How option( a) is correct....???​

Answer 1

tan 15°

as we subtract 30 from 45 we get 15

hence applying tan on both sides

Tan (45-30) = Tan 15

=====>>Tan (A+B) = Tan A - Tan B / 1+tan A tan B

writing this as such

Tan 15 = tan 45 - Tan 30 / 1 + tan 45 tan 30

1-1√3 / 1+1 √3

tan 15 = √3-1/√3+1

so this option is wrong

please brainliest mark if possible otherwise thanks
