~~4\sqrt{15} \left( 2\sqrt 2 + \sqrt 5 \right)\\\\=8\sqrt{15} \sqrt 2 + 4\sqrt{15} \sqrt 5\\\\=8\sqrt{15\times 2}+4 \sqrt{15 \times 5}\\\\=8\sqrt{30}+4\sqrt{3 \times 5 \times 5}\\\\=8\sqrt{30}  + 4 \sqrt{3\times 5^2}\\\\=8\sqrt{30} + 4\cdot 5 \sqrt 3\\\\=8\sqrt{30} +20\sqrt{3}

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
