Step-by-step explanation:

Las identidades trigonométricas se utilizan para resolver problemas de ángulos rectos.

De identidades trigonométricas:

sen\ \alpha=\frac{lado\ opuesto}{hipotenusa} \\\\lado\ opuesto=BC=a\\\\hipotenusa=b\\\\sen\ \alpha=\frac{lado\ opuesto}{hipotenusa} =\frac{BC}{b} \\\\sen\ \alpha =\frac{BC}{b}

The man or woman that entered the room was 55 years of age.

Step-by-step explanation:

If we add up all the ages together, it is 95. When the other person walks in, the mean changes to 25. If you do the math, or if you count, the man or woman that enters is 55, which when added together, gives 150. divided by 6 equals 25.
