যদি tan A \(= \frac{{15}}{8}\) এবং tan B \(= \frac{{7}}{24}\) তবে tan (A + B) =? A. 416/87 B. 87/416 C. 304/297 D. 297/304

tan(A + B) = (tan A + tan B)/(1 − tan A tan B). Numerator: 15/8 + 7/24 = 45/24 + 7/24 = 52/24. Denominator: 1 − (15/8)(7/24) = 1 − 105/192 = 87/192. So tan(A + B) = (52/24) × (192/87) = 416/87.
