Question

What is the answer to this question

Answer 1

Answer:

1

Step-by-step explanation:

$\cot( \alpha ) = \frac{1}{ \tan( \alpha ) }$

$\alpha_{lll} = \frac{5\pi}{4} - \pi \\ \\ \alpha_{lll} = \frac{\pi}{4}$

$\cot( \frac{\pi}{4} ) = \frac{1}{ \tan( \frac{\pi}{4} ) } \\ \cot( \frac{\pi}{4} ) = \frac{1}{ 1} = 1$
