It is transversal because it can separate two lines and become n perpendicular
Step-by-step explanation:
The answer is b, or 84ft squared. To find the area of a rectangle, you multiple the length by the width. So you multiply 10.5 by 8, which equals 84.
Additive property of equality states that:
if a=b, then a+c = b+c,
that is, if 2 quantities of the same value are added the same quantity, they are again equal.
In our problem a=AD, b=DB, and c= CD=DE
thus a+c=b+c means <span>AD + CD = DE + DE,
