Answer:

65 degrees

Step-by-step explanation:

<u>Step 1:  Find what the measure of JLK is</u>

JLM + JLK = 180

140 + JLK - 140 = 180 - 140

JLK = 40

<u>Step 2:  Find what the measure of KJL is</u>

KJL + JLK + JKL = 180

KJL + 40 + 75 = 180

KJL + 115 - 115 = 180 - 115

KJL = 65

Answer:  65 degrees

svlad2 [7]

De acuerdo a la información, se puede inferir que la probabilidad de cada empleado para ganarse un televisor es de 0.3. Por otra parte, la cantidad de televisores que maquilla cada empleado es 2.

<h3>¿Cómo calcular la probabilidad de cada empleado de ganarse un televisor?</h3>

Para calcular la probabilidad de cada empleado de ganarse un televisor utilizamos la siguiente formula:

  • P (probabilidad) = (casos favorables)/(casos posibles).

De acuerdo a la formula, solo tenemos que remplazar los valores, el número de casos favorables es 3 debido a que hay 3 televisores en total el sorteo, y el número de casos posibles, es 10 debido a que 10 empleados están participando en la rifa, como se muestra a continuación:

  • P = 3 ÷ 10
  • P = 0.3

<h3>¿Cómo calcular cuántos televisores maquilla cada empleado?</h3>

Para calcular cuántos televisores maquilla cada empleado debemos tener en cuenta que la empresa produce 20 televisores y que tiene 10 empleados. Entonces tenemos que dividir el numero de televisores en el número de empleados como se muestra a continuación:

  • 20 ÷ 10 = 2
