Question

1
If tan (A + B)= 13 and tan (A - B) = 13:09<A4B39", AB, find A and B.​

Answer 1

Answer:

A=Tan^-1 (13) ,B=0

Step-by-step explanation:

given

tan(A+B)=13 and tan(A-B)=13--------1

equating both  

tan(A+B)=tan(A-B)

then  A+B=A-B

        2B=0

          B=0

substitute in equation 1

then   tan(A+0)=13

tanA=13

     A=tan^-1 (13)
