Answer 1

PROBLEMA 1

$A = \sqrt{2} \sin(45) - 2 \tan(45) \\ A = \sqrt{2} \times \frac{1}{ \sqrt{2} } - 2 \times \frac{1}{1} \\ A = 1 - 2 \\ A = - 1$

PROBLEMA 2

$M = \frac{ \csc {}^{2}45 }{ \sec {}^{2} 45} \\ M = \frac{( \sqrt{2} ) {}^{2} }{( \sqrt{2}) {}^{2} } \\ M = \frac{2}{2} \\ M = 1$

PROBLEMA 3

$\frac{x}{ \tan(45) } = \frac{ \cot(45) }{x} \\ \frac{x}{1} = \frac{1}{x} \\ {x}^{2} = 1 \\ x = 1$

PROBLEMA 4

$\cot(45) = \frac{2x + 3}{6x - 5} \\ 1 = \frac{2x + 3}{6x - 5} \\ 6x - 5 = 2x + 3 \\ 6x - 2x = 3 + 5 \\ 4x = 8 \\ x = \frac{8}{4} \\ x = 2$

PROBLEMA 5

$3m \times \cot(45) = \csc {}^{2} 45 + 7 \tan(45) \\ 3m \times 1 = ( \sqrt{2} ) {}^{2} + 7(1) \\ 3m = 2 + 7 \\ 3m = 9 \\ m = \frac{9}{3} \\ m = 3$
