Answer:
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
We can see that Point R is at (3,6), and Point E is at (8,5).
Let's let (3,6) be (x₁, y₁) and let's let (8,5) be (x₂, y₂). So, substituting them into our formula, we'll get:
Subtract:
Square:
Add:
Approximate. Use a calculator:
So, the distance between RE is approximately 5.1 units.
And we're done!
