Question

What is the length of segment TR with T(-4,5) and R(2, -1)​

Answer 1

The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49

Explanation:

We need to find the length of segment TR with T(-4,5) and R(2, -1)​

The length of segment can be found using distance formula.

The distance formula is:
`Distance = √((x_2-x_1)^2+(y_2-y_1)^2)`

Putting values and finding length

We have:
`x_1=-4, y_1=5, x_2=2, y_2=-1`

`Distance = √((x_2-x_1)^2+(y_2-y_1)^2)\\Distance = √((2-(-4))^2+(-1-5)^2)\\Distance = √((2+4)^2+(-1-5)^2)\\Distance = √((6)^2+(-6)^2)\\Distance = √(36+36)\\Distance = √(72)\\Distance=8.49`

We found Distance = 8.49

So, The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49.
