In \(\triangle A B C, A=\tan ^{-1} 2\) and \(B=\tan ^{-1} 3\), then \(C =\) ____________
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(60^{\circ}\)
- D \(90^{\circ}\)
Answer & Solution
Correct Answer
(B) \(45^{\circ}\)
Step-by-step Solution
Detailed explanation
\(A+B+C = 180^{\circ}\) \(A+B = \tan^{-1} 2 + \tan^{-1} 3 = \pi + \tan^{-1}\left(\frac{2+3}{1-(2)(3)}\right)\)
