heya..!!!
sinA = √3/2
=> sinA = sin60
=> A = 60
AND,
COSB = √3/2
=> cosB = cos30
=> B = 30
we know that:-
tan ( A - B) = tanA - tanB/(1 - tanAtanB)
=> tan(60 - 30)
=> tan30 = 1/√3
sinA = √3/2
=> sinA = sin60
=> A = 60
AND,
COSB = √3/2
=> cosB = cos30
=> B = 30
we know that:-
tan ( A - B) = tanA - tanB/(1 - tanAtanB)
=> tan(60 - 30)
=> tan30 = 1/√3
