La medida aproximada del lado faltante según el teorema de desigualdad de triángulos es:
- más de 12 cm y menos de 48 cm
De acuerdo con el teorema de la desigualdad del triángulo que establece que;
La suma de la longitud de 2 lados cualesquiera de un triángulo debe ser mayor que el tercer lado.
Dado que :
a = 30 cm; b = 18 cm; c =?
Basado en el teorema de la desigualdad del triángulo;
- c debe ser <(a + b)
- c <(30 + 18); c <48 cm
- También c> (a - b)
- c> (30 - 18); c> 12 cm
Por lo tanto, el lado faltante debe ser menor que 48 y mayor que 12.

An example of an angle measurement problem is when trying to
calculate for the height of a particular object given the distance of the
observer from the object and the angle of elevation or depression. For example, you want to find out the height
of a building. All you need to know is the distance of your point of origin to
the building and the angle of elevation.
Answer:
Step-by-step explanation:

Hence proved!
<span>Because there are 20 coins plus four bars = 24 items to choose. You want to choose where to put the four bars, thus C(24,4). There are four bars, not five. Note that four bars divide the 20 coins into five sections. Five bars would divide it into six, but we only have five different kinds of coins to choose from.</span>
