Question

$\frac{\tan {47}^{\circ }}{\cot {43}^{\circ }}=1$.Is it true or false?

• A. True
• B. False
• C. Ambiguous
• D. Data insufficient
  

Answer 1

The correct option is A True

$tan{47}^0$
$=tan(90-{43}^0)$
$=cot\left({43}^0\right)$
Hence,
$=\frac{tan{47}^0}{cot{43}^0}$
$=\frac{cot{43}^0}{cot{43}^0}=1$
