Question

if tan=1/2& tabb=1/3 then A+B=​

Answer 1

Step-by-step explanation:

tan(A+B)=tanA+ tanB/1-tanA*tanB

tan(A+B)=1/2+1/3/1-1/6

=5/6/5/6

tan(A+B)=1

A+B=45°

Answer 2

1

Step-by-step explanation:

tan(A+B)= tanA+tanB/1-tanAtanB

=(1/2)+(1/3)/[1-1/2*1/3]

= [(3+2)/6]/[(6-1)/6]

= (5/6)/(5/6)

= 1
