What you have here is a situation with two <em>similar triangles. </em>The triangle in the lower left is similar to the triangle in the upper right - I've included an image with "cutouts" of those triangles so you can see the similarities. Similar triangles have a very important property: <em>the ratios of their corresponding sides are equivalent</em>. Here, we can set up a ratio between the sides of length 64 and x on the larger triangle, and the corresponding sides of length x and 36 on the smaller triangle. Setting the two equal to each other, we have

\frac{64}{x}= \frac{x}{36}

Multiplying both sides of the equation by 36 and x, we get

64\cdot36=x^2

finally, we take the square root of both sides of the equation to find x:

\sqrt{64\cdot36}=x\\&#10;\sqrt{64}\sqrt{36}=x\\&#10;8\cdot6=x\\&#10;48=x

Paha777 [63]

Answer:

distance apart= 9 miles

Step-by-step explanation:

The library , post office and gas station are all on elm street. The library is 3 miles away westward of the post office. The gas station is also 6 miles east of the post office. The distance between the library and the gas station can be computed below.

The post office is located at the middle between the library and the gas station. The library goes 3 miles westward of the post office while the gas station goes 6 miles eastward of the post office. The distance apart between the library and the gas station is the sum of the distance of the gas station from the post office and the distance of the library from the post office .

Therefore,

6miles  + 3 miles = 9 miles

The sum of 16 and a number x is equal to 19
Vladimir79 [104]

Answer:

x = 3

Step-by-step explanation:

We can write the equation as 16 + x = 19

To solve we can work backwards, I know the opposite of adding is subracting... so 19 - 16 = 3 which means x is equal to 3.

Hope that helps and have a great day!
