Answer:

Segment BC is (3d + 7)cm, where d=5. So, BC= 22cm.

Step-by-step explanation:

Segment BC is (3d + 7)cm, where d=5. You find this through these steps:

(5d-3)=(3d+7) Subtract 3d from 5d, which equals 2d.

2d-3=7 Now, add 3 to 7.

2d=10 Divide 10 by 2.

d=5 The solution is 5.

Plug 5 into the equation of Segment BC:

3(5) + 7

BC= 22

In order to name the coordinates, you read the X axis first and then the Y axis. So A would be (-4, 4). B would be (-4, 6). C would be (2, 4).

They are not congruent because each angle is a different measure.

Hope this helped! :)
