Question

if tan (A+B) = 1/3 and sec(5A-4B)=2 find value of A and B​

Answer 1

Answer:

this is ur answer.....

Answer 2

Answer:

sec (5A-4B) =2 = sec 60

Therefore 5A-4B = 60.......(1)

Similarly tan(A + B) = 1/3 does not fit with any angle. Please check, it could be 1/√3

Then A + B= 30......(2)

Then you can solve for A and B

B = 10 and A = 20
