Question

. If tan A=1/2

tan B =1/3

and then find the value ofA+B​

Answer 1

Step-by-step explanation:

tan A=1/2

tan B=1/3

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

=>tan(A+B)=(1/2+1/3)/(1-1/2×1/3)

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

=>tan(A+B)=(5/6)/(5/6)

=>tan(A+B)=1

=>tan(A+B)=tan pi/4

=>A+B= pi/4
