Question

if tan (A+B) = 1/root 3
itan (A-B) = 1
find A and B

Plz help me i will chose the brainlist Plzz help me plz I want the full solution this is of trigonometry chapter plzzz help me.......... ​

Answer 1

Step-by-step explanation:

1/√3 = tan 30 = tan (A+B)

1 = tan 45 = tan(A-B)

A+B = 30

and A= 30-B

A-B = 45 replacing A with it's value

(30-B) - B = 45

-2B = 45-30

-2B = 15

B = -15/2

A-B = 45

A - (-15/2) = 45

A = 45-15/2

A = 90/2 - 15/2

A = 75/2
