The correct answer is “Option C”. Note: In solution part we cut off tan B from cot B because they both are inverse of each other. Feb 18, 2025 ... If A=60 and B=30 verify at sin(A+B)=sinAcosB+cosAsinB | #pyq2024 #smartedutech #trignometry. https://www.youtube.com/. Like Comment. Share. Copy Dec 13, 2024 ... Given data, sin (A – B) = 1/2 But we know that sin 30° = 1/2 Thus, sin (A – B) = sin 30° A – B = 30° cos (A + B) = 1/2 But we know Sin A. Sin B = [Cos (A – B) – Cos (A + B)]/2; Sin A. Cos B = [Sin ( ... sinAa=sinBb=sinCc. In general, one of the three angles may be obtuse. The formula still holds true, although the geometric proof ...
