The degree measures of the angles of a triangle are represented by x, 3x and 5x -54.
lora16 [44]

Answer:

x = 26

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + 3x + 5x - 54 = 180 , that is

9x - 54 = 180 ( add 54 to both sides )

9x = 234 ( divide both sides by 9 )

x = 26

Escribe un número de tres cifras digamos a1b1c1, en el cual a1 sea distinto de c1; ahora invierte los dígitos a1 y c1, (obtendrá
Delicious77 [7]

Answer:

El número obtenido es:

  • <u>1089</u>.

Step-by-step explanation:

Vamos a escoger tres números sencillos para cada variable como:

  • a1 = 1
  • b1 = 2
  • c1 = 3

Por lo tanto, nuestro número de tres cifras es:

  • 123 (la única pauta es que a1 sea diferente a c1 y con este número la cumplimos)

Ahora, nos dice que invirtamos los números a1 y c1, por lo tanto, nuestro nuevo número de tres cifras sería:

  • 321

A continuación, nos menciona que restemos el menor del mayor, en este caso, nuestro número menor es 123 y el mayor es 321, por lo tanto:

  • 321 - 123 = <u>198</u> (Este resultado será el mismo sin importar cuáles números elijas para el ejercicio)

Como obtuvimos el número 198, se podría decir que:

  • a2 = 1
  • b2 = 9
  • c2 = 8

Ahora nos piden que invirtamos a2 y c2, por lo tanto nuestro nuevo número sería:

  • <u>891</u>

Y por último, nos solicita que sumemos los dos últimos números obtenidos, entonces tenemos:

  • 891 + 198 = <u>1089</u>

Por lo tanto, <u>el número obtenido al final es 1089</u>, el cual obtendrás sin importar qué número de tres cifras elijas al inicio, siempre y cuando no se repitan el primero y el tercer dígito.
