Web3 jan. 2024 · sin (A + B) = √3/2 and tan (A - B) = 1/√3 Concept Used: sin 60° = √3/2 tan 30° = 1/√3 Calculation: sin (A + B) = √3/2 as we know sin 60° = √3/2 (A + B) = 60 ---- (i) tan (A - B) = 1/√3 We know tan 30° = 1/√3 (A - B) = 30 ---- (ii) Add equation i and ii A = (60 + 30) / 2 A = 45° B = (60 - 30) / 2 B = 15° 2A + 3B = 90 + 45 = 135° Web4 jun. 2024 · Explanation: Since 0 < A < 90o we know that ∠A is in the first quadrant. Consider the right OAB where O is the origin and side AB is opposite ∠A We are told that sinA = 1 3 ∴ side AB = 1 and side OA = 3 Applying Pythagoras (OA)2 = (AB)2 + (OB)2 ∴ 32 = 12 + OB2 OB = √9 −1 [Since OB > 0 because ∠A is in the first quadrant] OB = √8 = 2√2 gary stephenson and snakes https://1stdivine.com
