To start, write your locations as points, with north and south being positive and negative y respectively and east and west being positive and negative x respectively. Doing this gives us the mall at (-3,-2) and the park at (4,5). Now, we use our distance formula ( \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 } ) to solve for the unknown distance. Plugging in with the park values as our second values and our mall values as our first values (as well as with our unknown distance as d), we get d= \sqrt{(4-(-3))^2+(5-(-2))^2} = \sqrt{(7)^2+(7)^2} = \sqrt{49+49} = \sqrt{98}. This square root can be rounded to 9.9 miles.

SIZIF [17.4K]

Answer:

4

Step-by-step explanation:

If x is the third number, then x−1 and x−2 are the second and first numbers.

10(x−2) + 10(x−1) = 10 + 10x

x − 2 + x − 1 = 1 + x

2x − 3 = 1 + x

x = 4

Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.

Add like terms to get 5x - 20 = 180
5x = 200
x = 40
