Line t intersects line u as shown below <br><br><br> What is the value of x
Rudiy27

Answer:

x = 117 degrees

Step-by-step explanation:

Find the diagram attached

From the diagram, the angle at the top left on line t is equal to theta of the top left on line u and is equal to 117 degrees (corresponding angle)

Also the angle angle on the top left on line u will be equal to x (vertically opposite angle)

Hence the value of x = 117 degrees (vertically opposite to each other on line u)

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.
