For 3 you have to subtract 72 on both sides
+72 -2X=54
-72 -72
72-72 cancels out and then subtract the 54 from -72 the answer for that then should be divided by -2
and then X= (the answer)
and the -72 goes under 54 not -2x
Answer:
the additional cost to produce each phone
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
