Question

Yeah the picture sums it up, I just dont remember how to do this

Answer 1

Answer and Step-by-step explanation:

To find the length of AB, we have to use Distance Formula.

Distance Formula takes two points on a graph, and puts it into the following formula to calculate the distance between those two points.

The formula:

D =
`\sqrt{(x_(2) - x_1)^2 + (y_2 - y_1)^2 }`

Where:

D = The Distance between two points

`x_2` = The x value of the second point

`x_(1)` = The x value of the first point

`y_2` = The x value of the second point

`y_(1)` = The x value of the first point

Point A will be the first point and point B will be the second point. All we have to do now is plug those points into the formula and solve.

`√((10 - 5)^2 + (0 - 10)^2 )\\\\\\\\√((5)^2 + (- 10)^2 )\\\\\\\\√(25 + 100 )\\\\\\\\√(125)\\\\\\\\√(125) = 5√(5)`

The length of side AB is
`5√(5)` units, or 11.18 units.

I hope this helps!
