Step-by-step explanation:
The angle of depression is formed by the line of sight and the horizontal line tangent to the top of the observer.
To make a perfect square, we must know that 22/2 = 11. In this case:
(x + 11)^2 = x^2 + 22x + 121
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,
by the </span><span>Addition Property
Answer: </span><span>Addition Property
