Answer:
.
Step-by-step explanation:
The linear approximation is given by the equation

Linear approximation is a good way to approximate values of
as long as you stay close to the point
, but the farther you get from
, the worse your approximation.
We know that,

Next, we need to plug in the known values and calculate the value of
:

Then
.
Answer:
The length AD is greater than length BD.
Step-by-step explanation:
Hinge theorem states that if two triangles have two congruent sides then the triangle with the larger angle between those sides will have longer third side
In ΔACD and ΔBCD

So side opposite to greater angle is greater side
Therefore, length AD is greater than length BD.
