Answer:
Step-by-step explanation:
a = BC - DC
= tan 28°
BC = ≈ 112.8 m
DC = ≈ 43.6 m
a ≈ 112.8 - 43.6 = <em>69.2 m</em>

The value of a is
Step-by-step explanation:
<u>1. Determine the other solution of x</u>
If one value is 5 + then the other value is 5 -
<u>2. Use reverse technique to find the equation</u>
(5 + ) (5 -
) = 0
25 - +
-
= 0
- + 25 = 0
<u>3. The equation is</u> - + 25 = 0
<u>4. Find the value of a</u>
a is the number with the variable therefore it is -

The box should have base 52 cm by 52 cm and height 26 cm.
What is volume?
A three-dimensional space's occupied volume is measured. It is frequently expressed as a numerical value using SI-derived units, other imperial units, or US customary units. Volume definition and length definition are connected.
The Volume of a box with a square base x by x cm and height h cm is
Since the surface area directly affects the amount of material used, we can reduce the amount of material by reducing the surface area.
The surface area of the box described is
We need A as a function of x alone, so we'll use the fact that
⇒
So, the area becomes,
We want to minimize A, so
The second derivative test verifies that A has a minimum at this critical number:
which is positive at x = 52.
Now,
Hence, The box should have base 52 cm by 52 cm and height 26 cm.
