Take a look at the streets in Phoenix. N 9th Avenue, N 10th Avenue, N 11th Avenue, N 12th Avenue, and N 13th Avenue are parallel, and they intersect W Roosevelt Street and Phoenix-Wickenburg Hwy. The distance between N 15th Ave. and N 13th Ave., represented by segment AB, is 530 feet along W Roosevelt St. The distances between N 13th Ave. and N 12th Ave. (segment BC), between N 12th Ave. and N 11th Ave. (segment CD), between N 11th Ave. and N 10th Ave. (segment DE) and between N 10th Ave. and N 9th Ave. (segment EF) are all the same, 340 feet. Now let's find some distances between these avenues along Phoenix-Wickenburg Hwy. (segment AL).

If the distance on Phoenix-Wickenburg Hwy between 13th Avenue and 11th Avenue, represented by segment GJ is approximately 1060 feet, how long is Phoenix-Wickenburg Hwy. between 13th Avenue and 15th Avenue (segment AG) to the nearest foot?

1652 feet

826 feet

340 feet

530 feet

Respuesta :

it will be 530 or 826


Answer:

The correct option is 2.

Step-by-step explanation:

Let the distance on Phoenix-Wickenburg Hwy between 13th Avenue and 15th Avenue be AG = x.

From the given diagram it is clear that the distance on Phoenix-Wickenburg Hwy is represented by a straight line.

In triangle ABG and ADJ,

[tex]\angle A=\angle A[/tex]            (Reflexive property)

[tex]\angle ABG=\angle ADJ[/tex]            (Right angle)

By AA property of similarity,

[tex]\triangle ABG\sim \triangle ADJ[/tex]

The corresponding sides of similar triangles are proportional.

[tex]\frac{AB}{AD}=\frac{AG}{AJ}[/tex]

[tex]\frac{AB}{AB+BC+CD}=\frac{AG}{AG+GJ}[/tex]    (Segment addition postulate)

Substitute AB=530, BC=340, CD=340, AG=x and GJ=1060 in above equation.

[tex]\frac{530}{530+340+340}=\frac{x}{x+1060}[/tex]

[tex]\frac{530}{1210}=\frac{x}{x+1060}[/tex]

[tex]\frac{53}{121}=\frac{x}{x+1060}[/tex]

On cross multiplication we get

[tex]53(x+1060)=121x[/tex]

[tex]53x+56180=121x[/tex]

Subtract 53x from both the sides.

[tex]56180=121x-53x[/tex]

[tex]56180=68x[/tex]

Divide both sides by 68.

[tex]\frac{56180}{68}=x[/tex]

[tex]826.17647=x[/tex]

[tex]x\approx 826[/tex]

The distance on Phoenix-Wickenburg Hwy between 13th Avenue and 15th Avenue is 826 feet. Therefore the correct option is 2.
