Question

The vertices of triangle ABC are as

follows:
A: (0, 6)
B: (0, -3)
C: (-3, 4)
What is the length of side AB?
Solution:​

Answer 1

The length of side AB is 9 units.

Explanation:

In order to find this answer, you must use the distance formula.

`√((x_2 - x_1)^2 + (y_2 - y_1)^2)`

x2 = 0

x1 = 0

y2 = -3

y1 = 6

Since both x values are equal to zero, we do not need to plug these into our formula. It will just cancel out. Therefore, just plug in the y values.

`√((-3-6)^2)`

-3 - 6 = -9

(-9)^2 = 81

sqrt(81) = 9 units
