Question

Tommorrow is my exam plz solve briefly​

Answer 1

Answer:

Tan (A+B ) = root 3                         A+B = 60

tan (A-B) = 1/root 3                         A-B =30

On solving we get A = 45 degrees and B = 15 degrees

Answer 2

Answer: TT Step-by-step explanation: Tan (A + B) = √3,   Tan ( A + B) = Tan 60              A + B = 60 Tan ( A - B) = 1/√3,  Tan (A - B) = Tan 30 A - B = 30 A + B = 60 A - B = 30 adding we get.. 2A = 90 , A = 90/2 = 45  Sin(A + B)tan A + CosA  Tan (A - B) Sin60 tan45 + cos 45 Tan 30 √3/2 (1) + 1/√2 (1/√3) √3/2  + 1/√6 = √3/2 + √6/6 = √3 (3 + √2)/6
