Question

if tan alpha + beta equal to 1 by 2 and tan Alpha equal to 1 by 3 then tan beta equal to​

Answer 1

Answer: 1/6

Step-by-step explanation:

Let alpha be a

Let beta be b

Tan (a+b)=1/2

Tan a +tan b=1/2

Given that tan a=1/3

1/3+tan b=1/2

Tan b=1/2-1/3

Tanb=3-2/6

=1/6

Answer 2

Answer:

1/6

Step-by-step explanation:

tan (alpha+beta)=1/2

tan alpha =1/3

tan alpha +tan beta=1/2

1/3+tan beta=1/2

tan beta=1/2-1/3

tan beta=1/6
