A piece of wire 23 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral tria
AURORKA [14]

Answer:

For maximum area, all of the wire should be used to construct the square.

The minimum total area is obtained when length of the wire is 10m

Step-by-step explanation:

For maximum,  we use the whole length

For minimum,

supposed the x length was used for the square,

the length of the side of the square = x/4m

Area = \frac{x^{2} }{16}

For the equilateral triangle, the length of the side =  \frac{23 - x}{3}

Area = \frac{\sqrt{3} }{4}  a^{2}  = \frac{\sqrt{3} }{4} (\frac{23 - x}{3} )^{2}

Total Area = \frac{x^{2} }{16}  + \frac{\sqrt{3} }{36} (23-x)^{2}

\frac{dA}{dx}  = \frac{x}{8}  -  \frac{\sqrt{3} }{18} (23 - x)\\

\frac{d^{2}A }{dx^{2} }  = \frac{1}{8}  + \frac{\sqrt{3} }{18}  > 0, therefore it is minimum

\frac{dA}{dx}  = 0 \\\\

\frac{x}{8}  -  \frac{\sqrt{3} }{18} (23 - x) = 0\\

x = 10.00m

The vertex and sides of the angles are:

  • Lines: EF and FG; Angle: Angle F
  • Lines: GH and HI; Angle: Angle I

The angles are:

  • <B, <ABC, <CBA and ^B
  • <L, <KLM, <MLK and ^L

<h3>How to determine the angles and the vertices?</h3>

<u>The measure of the angles</u>

Here, there is no parameter to determine the measure of each angle.

This means that the measures of angles cannot be calculated; however, the angles can be classified.

The classification of the angles are:

  • Acute angle
  • Obtuse angle
  • Obtuse angle
  • Acute angle

<u>The vertex and sides of the angles</u>

The vertex is the point where two lines meet, while the sides are the lines

So, the vertex and sides of the angles are:

  • Lines: EF and FG; Angle: Angle F
  • Lines: GH and HI; Angle: Angle I

<u>Name each angle in four way</u>

The vertex is the point where two lines meet, while the sides are the lines

In this case, the angles are:

  • <B, <ABC, <CBA and ^B
  • <L, <KLM, <MLK and ^L
