 Hello friends and how are you all doing today? My name is Priyanka and that is just us a question. It says if tan A plus B is equal to root 3 and tan A minus B is equal to 1 by root 3, because B is less than equal to 90 degrees but greater than 0 degrees and if A is greater than B then we need to find A. Let us rewrite whatever is given to us in the question. Before that we should be well versed that the value of tan 60 degrees is equal to root 3 and the value of tan 30 degrees is equal to 1 by root 3. Right? Are given that tan root 3, isn't it? But we have learned in our previous classes that the value of root 3 is equivalent to tan 60 degrees. So this implies we can write that is equal to degrees. So this implies that the value of A plus B will be equal to 60 degrees, isn't it? Let us take this equation as 1. We are given that tan B is equal to 1 by root 3 but 1 by root 3 is equivalent to tan 30 degrees. So this implies that tan A minus B will be equal to tan 30 degrees and this further implies that A minus B is equal to 30 degrees. Right? Let it be the second part, the first equation and the second equation we get plus B plus A minus B is equal to 60 degrees plus 30 degrees. Simplifying, we have 2A equal to 90 degrees. This further implies we have the value of A as 45 degrees and if A plus B is equal to 60 degrees and A is 45 degrees then that implies the value B is equal to 15 degrees, isn't it? So the answer for this question is the value of angle A is 45 degrees and the value angle B is equal to 15 degrees. Right? So hope the solution is clear to you. Do take care of your calculation and hope to see you next time.
