Question

$\frac{\tan 47°}{cot43°}=1$. Write ‘True’ or ‘False’ and justify your answer.

• A. True
• B. False

Answer 1

The correct option is A True

$\frac{\tan 47°}{cot43°}$

We know that $\tan (90°-\theta )=cot\theta$

$\frac{\tan 47°}{cot43°}=\frac{\tan (90°-43°)}{cot43°}$

$=\frac{cot43°}{cot43°}=1$
