If `tan A=(1)/(2) and tan B=(1)/(3)`, then which of the following is true ?
A. `A+B=(pi^( c))/(4)`
B. `A-B=(pi^( c))/(4)`
C. `2A+B=(pi^( c))/(4)`
D. `A+2=(pi^( c))/(4)`
A. `A+B=(pi^( c))/(4)`
B. `A-B=(pi^( c))/(4)`
C. `2A+B=(pi^( c))/(4)`
D. `A+2=(pi^( c))/(4)`
Correct Answer – A
Apply ` tan(A+B)=(tan A + tan B)/( 1- tan A tan B)`
