По теореме Пифагора найдем LM

$lm = \sqrt{km^{2} - kl^{2} }$

$lm = \sqrt{289 - 64}$

$lm = \sqrt{225}$

LM=15

$\cos(m) = \frac{lm}{km}$

$\cos(m )= \frac{15}{17}$

$\sin(m) = \frac{kl}{km}$

$\sin(m) = \frac{8}{17}$

$\tan(k) = \frac{lm}{kl}$

$\tan(k) = \frac{15}{8}$

$\tan(k) = 1 \frac{7}{8}$

$\tan(k) = 1.875$

$\cot(k) = \frac{kl}{lm}$

$\cot(k) = \frac{8}{15}$
