Which statement best explains the relationship between lines CD and FG? They are perpendicular because their slopes are equal.

They are perpendicular because their slopes are negative reciprocals.

They are not perpendicular because their slopes are equal.

They are not perpendicular because their slopes are negative reciprocals.

B. They are perpendicular because their slopes are negative reciprocals

Step-by-step explanation:

see attachment for missing graph.

Two coordinates of the blue line (-4,0) and (4,2).

In order to find the slope of blue line:

Coordinates of the green line are (-2,4) and (0,-4).

To find the slope of green line:

The above slope are negative reciprocal of each other.

Therefore, B is correct option

(B) They are perpendicular because their slopes are negative reciprocals

Step-by-step explanation:

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
