If ∝ + ß = \(\frac{π}{2}\) and ∝ : ß = 2 : 1 then ratio of tan∝ to tanß is? |
\(\sqrt {3 }\) : 1 3 : 1 1 : 3 2 : 1 |
3 : 1 |
∝ + ß = \(\frac{π}{2}\) ⇒ 2\(x\) + \(x\) = \(\frac{π}{2}\) ⇒ 3\(x\) = \(\frac{π}{2}\) \(x\) = \(\frac{π}{6}\) tan∝ = tan\(\frac{π}{3}\) = \(\sqrt {3}\), tanß = tan\(\frac{π}{6}\) = \(\frac{1}{\sqrt {3 }}\) tan∝ : tanß = \(\sqrt {3 }\) : \(\frac{1}{\sqrt {3 }}\) = 3 : 1 |
