Question

if tan Alpha equal to 1 by 2 and 10 B equal to 1 by 3 and 10 alpha + beta equal to tan A + tan b 1 upon 1 minus tan a tan B find the value of alpha + beta​

Answer 1

Answer:

tanα=1/2

tanβ=1/3

Now, tan(α+β)=tanα+tanβ/1-tanα.tanβ

=1/2+1/3 / 1- 1/2.1/3

=5/6 / 1- 1/6

=5/6 / 5/6

=1

tan(α+β)=1

(α+β)=45°
