Answer:
[tex]-2.813[/tex]
Step-by-step explanation:
Se simplifica inicialmente la fórmula en términos de las funciones trigonométricas fundamentales (Initially, the formula is simplified in terms of fundamental trigonometric functions):
[tex](\sec 245^{\circ} + \tan 45^{\circ} )\cdot \cot 37^{\circ} - 2\cos 60^{\circ}[/tex]
[tex]\left(\frac{1}{\cos 245^{\circ}}+\frac{\sin 45^{\circ}}{\cos 45^{\circ}} \right)\cdot \left(\frac{\cos 37^{\circ}}{\sin 37^{\circ}} \right) - 2\cdot \cos 60^{\circ}[/tex]
[tex](-2.366 + 1 )\cdot (1.327) - 1[/tex]
[tex]-2.813[/tex]
