Your answer would be, For example, the Triangular section of a lawn is named ABC, The sides are name ABC, respectively as the opposite of the angles, with the similar letters. Like Side A is opposite angle (a). The missing side length is B, To get this, Maurice, used the Law of Cosines. In order to use this, Maurice need to have two sides, and angle between them, that is given to solve for the missing lengths, which is Sides A, and C, and an angle B. Johanna used the Law of Sines, in which, she need two angles, and an opposite sides, that should be given to find the missing Length, which is Angle B, and C, and Side C. So, Since both Laws use the remaining were given, The use of both, will result in a similar measurements.

Svetlanka [38]

La pregunta está incompleta ya que no se da el costo de la colocación de baldosas por m².

Suponga que el costo de los mosaicos por m² = c

Respuesta:

39.06c

Explicación paso a paso:

El costo del embaldosado será:

El costo por m² * área total a embaldosar

Dado que :

La dimensión de la habitación a embaldosar es:

Longitud = 9,30 metros

Ancho = 4.20 metros

El área total de la habitación a embaldosar es = Largo * ancho

Área total de la habitación a embaldosar = 9,30 m * 4,20 m

Superficie total de la habitación a embaldosar = 39,06 m²

Si el costo del mosaico por m² = c

El costo de embaldosar la habitación será:

39,06 * c = 39,06c
