Question

Angle ABC has A(3-,6), and C(9,55 as it vertices.
What is the length of side AB in units?

Answer 1

7.07 units

Explanation:

Given

`A = (-3,6)`

`B = (2,1)`

`C = (9,5)`

Required

Side length AB

To do this, we make use of the following distance formula;

`d = √((x_1 - x_2)^2 + (y_1 - y_2)^2)`

So, we have:

`d = √((-3 - 2)^2 + (6 - 1)^2)`

`d = √((-5)^2 + 5^2)`

`d = √(25 + 25)`

`d = √(50)`

`d = 7.07`
