Step-by-step explanation:
For 2, AB is parallel to CD as AD is also parallel to BC
For 3, you can also say AD is parallel to BC

To find the area of rectangle, you multiple length by width, so that would be

Since we are talking about area \ length, x need to be positive so we don't need to worry about absolute value now.
#22
The area of triangle is

, so that would be

Hope this helps.
The interior angles in any triangle sum to 180 degrees, so the measure of angle E is 180 - 65 - 50 = 65 degrees.
Assuming side d is opposite angle D, side e is opposite angle E, and side f is opposite angle F, we can use the law of sines to determine the side lengths e and f.


Angles E and F have the same measure, so
as well.
Answer:
Slope is -2
