Answer:
4.5 units
Step-by-step explanation:
The formula given is used to calculate the length of a segment given the coordinates of the endpoints.
let (x₁, y₁ ) = A(-1, 1) and (x₂, y₂ ) = (3,3), then
AB =
=
= =
≈ 4.5 ( nearest tenth )
Answer:
Option 1 is correct that is square root of 18.
Step-by-step explanation:
We will use pythagoras theroem to find the length of hypotenuse
Here, c is hypotenuse,a is one leg and b is the other leg.
Here, a=b=3
On substituting the values in the formula we get:
Hence, Option 1 is correct that is square root of 18.
