A b 3 4 and 8a+5b=22 then-If tan (A B) = √3 and tan (A – B) = \(\frac{1}{\sqrt 3}\) 0° < A B ≤ 90°;(a b)^3 can be written as, (a b) * (a b) * (a b) Let's multiply the first two terms (a b) * (a b) * (a b) a*a a*b b*a
0° < A B ≤ 90°;Math a^3 b^3 = (a b)(a^2 b^2 ab) /math Lets try to derive this expansion from the expansion of math (a b) ^ 3 /math We have, math(a b) ^ 3 = a^3A > B, find A and B Given that Our equations are A B = 60° (1) A – B = 30° (2) Adding (1) and (2) A B A – B = 60° 30° 2A = 90° A = (90°)/2 A = 45° Putting A = "45°" in (1) A B = 60° 45° B = 60° B = 60° − 45° B = 15° Hence A = 45° , B = 15°
