Answer:
100°
Step-by-step explanation:
The ratio of angles of the triangle is 2:2:5. We know that the angle sum property of the triangle is 180°. So that , let the ratio be 2x : 2x : 5x .
=> 2x + 2x + 5x = 180°
=> 9x = 180°
=> x = 180°/9
=> x = 20°
Here the largest ratio is 5x . Therefore the largest Angle is ,
=> Largest Angle = 5x
=> Largest Angle = 5 × 20°
=> Largest Angle = 100°
<h3>
• Hence the largest Angle is 100° </h3>

Answer:
El pH del refresco es 3.42.
Step-by-step explanation:
Se puede calcular el pH del refresco usando la siguiente fórmula:
![pH = -log([H^{+}])](https://tex.z-dn.net/?f=pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29)
En donde:
[H⁺]: es la cocentración de los iones H⁺ de la solución
Entonces, el pH es:
![pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42](https://tex.z-dn.net/?f=pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29%20%3D%20-log%283.8%5Ccdot%2010%5E%7B-4%7D%29%20%3D%203.42)
El resutlado obtenido nos permite concluir que ese refresco es ácido.
Por lo tanto, el pH del refresco es 3.42.
