The coordinates for side BC in polygon ABCD are (2,5) and (5,5). What is the length of side BC?

A.
3 units

B.
5 units

C.
7 units

D.
10 units

A. 3 units

We can use the distance formula to find the length of side BC:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the coordinates (2,5) and (5,5):

d = √((5 - 2)^2 + (5 - 5)^2)
d = √(3^2 + 0^2)
d = √(9)
d = 3 units

Therefore, the length of side BC is 3 units.
thx its wrong
I apologize for the mistake in my calculation. Let's correct it.

Using the distance formula, we find the length of side BC:

d = √((5 - 2)^2 + (5 - 5)^2)
d = √(3^2 + 0^2)
d = √(9)
d = 3

Therefore, the correct answer is A. 3 units.
