Evaluate that question ​

Answer 1

Answer:

tan(A+B) = √3.....(1)

and cosec(A-B)= 2......(2)

from ...(1)

we conclude that

A+ B = 60 .. (3) as tan60 = √3

and from...(2)

we get

A-B = 30 ....(4) as cosec30 = 2

add (3) and (4)

we get 2A = 90

A = 45

put this in (3)

we get B= 15

thus the value of A= 45 and B = 15
