Find the value of x<br><br>m&lt;2 = 9x - 1​
jasenka [17]

Answer: x=9

Step-by-step explanation:

The bottom triangle that has a 40° is an isosceles triangle, therefore the other angle at the bottom right is also 40°. This leaves the top angle to be 100°.

180=40+40+x

180=80+x

x=100

Now, to find ∠2, you can tell it is a supplementary angle. Therefore, the 2 angles add up to 180°

180-100=∠2

80°=∠2

The problem states that ∠2 is 9x-1. We know that ∠2 is 80°. We can solve for x.

80=9x-1

81=9x

x=9

Marcos gana S/18,50 por hora y se le descuenta
Talja [164]

Answer:

$76,9

Step-by-step explanation:

Para calcular cuánto ganó Marcos ese día, tienes que multiplicar el salario por hora por el número de horas que trabajó y restarle el valor por los minutos que llegó tarde que es el resultado de multiplicar los minutos que llegó tarde por el valor a descontar por minuto:

salario: $18,50 por hora

número de horas trabajadas: 5

descuento por tardanza: $1,20 por minuto

número de minutos de tardanza: 13 minutos

salario del día=($18,50*5)-($1,20*13)

salario del día=$92,5-$15,6

salario del día=$76,9

De acuerdo con esto, el salario que Marcos ganó ese día es $76,9.
