Question

21. If tan(A - B)=1, and sec(A + B) =2/√3 find the smallest positive
values of A and B and also their most general values.​

Answer 1

Step-by-step explanation:

tan(A-B)=1

A-B=45. 1st equation

Sec(A-B)=2√3

A-B=30. 2nd equation

Add 1st and 2nd equation

2A=75

A=75/2

Substitute A value in 1st equation

(75/2)-B=45

B=45-(75/2)

B=15/2
