Kobotan [32]3 years ago

Answer:

This question confused the heck out of me, but I tried my hardest. Here you go:

Step-by-step explanation:

I solved the problem with sin and cos and all that, and I got 2.81859485365.

When I divided pi by 2, I got 1.57079632679 . So basically, the problem that was supposed to show that 0<C<pi/2 is correct is incorrect. Does that make sense? If not, just ask in the comments, and I'll edit this answer.

~Plz mark brainliest!~

Si la amplitud del complemento de un ángulo agudo es mayor, menor o igual que la del suplemento de un ángulo agudo. ¿podes respo
Harrizon [31]

Answer:

Dados dos ángulos vecinos, ambos son complementarios si la suma de sus medidas es igual a 90° y suplementarios si esa suma de medidas es igual a 180°. Puesto que uno de los ángulos es el ángulo agudo mencionado en el enunciado, es decir, un ángulo cuya medida es mayor que 0° y menor que 90°. Entonces, el ángulo complementario debe ser inevitablemente menor que el ángulo suplementario.

Step-by-step explanation:

Dados dos ángulos vecinos, ambos son complementarios si la suma de sus medidas es igual a 90° y suplementarios si esa suma de medidas es igual a 180°.
