Question

HEY GUYS plz give ANSWER fast...

Answer 1

Given, Tan (A+B) = root (3)

And, Tan (A-B) = 1/root(3)

[Taking Tan inverse on both sides :]

Tan inverse [root3] = 60 .. (since Tan 60 = root 3)

Tan inverse [1/root3] = 30 .. (since Tan 30 = 1/root3)

Hence,

A+B = 60 ....... (i)

A-B = 30 ........ (ii)

Adding equations (i) & (ii)

2A = 90

A = 45 degree

Hence, A+B = 60

B = 60-A = 60 - 45 = 15 degree

Answer: A = 45 degree, B = 15 degree

Hope it helps.
