If sin (A+B)=1 and tan (A-B)=1/sqroot 3<br><br> are acute angles. find out the value of A and B​
Nataliya [291]

Answer:

A = 60° , B = 30°

Step-by-step explanation:

sin(A+B ) = 1\\\\\  \  \ (A + B) \  = \ \ sin^{-1} 1\\\\A + B = 90^\circ  --(1)\\\\ \ tan (A - B) = \frac{1}{\sqrt{3}}\\\\(A-B) = tan^{-1}\frac{1}{\sqrt3}}\\\\A - B =  30^\circ --(2)\\\\ (1)  + (2) => 2A = 120^\circ\\

                   A = 60^\circ

from \ (1) \\A + B = 90^\circ\\60^\circ + B = 90^\circ\\B = 90^\circ - 60^\circ\\B = 30^\circ
