Answer:

 X=32°

 Y=122°

Z=58°

Step-by-step explanation:

 X+73°+75°=180° (interior angles of a triangle adopts to 180°)

 X=180°-148°

 X=32°

 32°+Y+26°=180°(interior angles of a triangle adopts to 180°)

 Y=180°-58°

 Y=122°

Y+Z=180(angle on straight line adopts to 180°)

Z=180°-122°

Z=58°

Answer:

x=32, y=122, z=58

Step-by-step explanation:

En la casa de la familia de Trevor viven 6 personas (incluyendo a Trevor) y hay 3 baños. En el último mes, cada
persona se bañó durante un promedio de 480 minutos y utilizó un promedio de 72 litros de agua al bañarse
(en todo el mes). El agua cuesta 0.20 dólares por litro.
¿Cuánto dinero gastó la familia de Trevor en total en agua al bañarse el mes pasado?
dólares.

Answers

Answer:

La familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.

                                                       

Step-by-step explanation:

El costo del agua viene dado por:

[tex] C = \$0.20/L [/tex]   (1)

Y cada persona de la familia de Trevor gasto en promedio 72 litros de agua. Si la familia tiene 6 integrantes (incluido Trevor) entonces:

[tex] A = 72 L*6 = 432 L [/tex]    (2)

Entonces, toda la familia usó 432 litros de agua en promedio en todo el mes.

Para saber el dinero total gastado por la familia debemos multiplicar la ecuación (1) y la ecuacion (2):

[tex] C = \$0.20/L*432 L = \$86.4 [/tex]

Por lo tanto, la familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.

Espero que te sea de utilidad!                                    

Usando proporciones, hay que la familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.

En la casa, hay 6 personas.Cada persona utilizó un promedio de 72 litros de agua.

Por eso, en todo, 6 x 72 = 432 litros de agua fueron usados.

Cada litro cuesta $0.2. De esa forma, el total de dinero gasto es de:

T = 0.2 x 432 = 86.4.

La familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.

Answers

Answer:

48% is A and since i like quarters more than nickels and dimes its c for 30

Step-by-step explanation: Because I said so.

Answer:

To calculate the average you must add the percentages up and divide by the number of percentages. So, 52+28+34+95+16+63=288/6=48. The percentage is 48%.

For the second questions you take 100 divide by 3 since there are 3 coins and you get an 33.3%. But, since you can't have 0.3 of a coin. So, since you started with a nickel, you would end with a nickel giving you a percentage of 34% and the dimes and quarters a percentage of 33% each.

In the figure shown, which theorem can be used to show that △ABC ≅ △DEF?

Answers

Answer:

option C, AAS triangle congruence theorem

hope it helps you

AAS triangle congruence theorem is used to show ΔABC≅ΔDEF

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

We need to find which theorem is used to show ΔABC≅ΔDEF

The two triangles are congruent.

AB=DE

BC=FE

CA=DF

and ∠A=∠D

∠B=∠E

If any two angles and side included between the angles of one triangle are equivalent to the corresponding two angles and side included between the angles of the second triangle

By AAS, When two angles and a non-included side of a triangle are equal to the corresponding angles and sides of another triangle, then the triangles are said to be congruent.

Hence AAS triangle congruence theorem is used to show ΔABC≅ΔDEF
