Explicación paso a paso:
1. falso
[tex] \sin(45°) + \cos(45°) = 1[/tex]
Calculamos,
[tex] \frac{ \sqrt{2} }{2} + \frac{ \sqrt{2} }{2} = 1[/tex]
Calculamos La Suma
[tex] \frac{ \sqrt{2} + \sqrt{2} }{2} = \frac{2 \sqrt{2} }{2} = \sqrt{ 2 } [/tex]
Elevamos Al Cuadrado
[tex]( \sqrt{2} {}^{2} = 1 {}^{2} [/tex]
Eliminamos Parentesis
[tex]2 = 1[/tex]
2. falso
[tex] \sin(180° + 30°) = \sin(30°) [/tex]
Sumamos Los Parentesis
[tex] \sin(210°) = \sin(30°) [/tex]
[tex] - \frac{1}{2} = \frac{1}{2} [/tex]
Espero Te Sirva, Saludos JB.
