The trigonometry illustrates that the four angles whose cosine is the same as cos pi/3 will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3
<h3>How to illustrate the information?</h3>
From the information, given cos (x), the value that is similar to cos x will be the sum of the angle and multiple of 360.
Therefore, for the angle cos(∏/3), the angles that are similar to this angle will be expressed as Cos(2∏n + ∏/3) where n is any positive integer.
Then the other four angles will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3. Also, the statement that all angles that have the same cosine will have the same sine is false. The sine of an angle is simply equal to the cosine of the complementary angle.

The volume of the diamond is 137.1 cm³. The correct option is the last option 137.1 cm³
<h3>Density, Mass and Volume </h3>
From the question, we are to calculate the volume of the diamond
Using the formula,
Density = Mass/ Volume
Then, we can write that
Volume = Mass/ Density
From the given information,
Mass of the large diamond = 481.3 grams (g)
Density of the diamond = 3.51 grams/ centimeters cubed (g/cm³)
Putting the parameters into the formula, we get
Volume = (481.8 g)/ (3.51 g/cm³)
Volume = 137.1225 cm³
Volume ≈ 137.1 cm³
Hence, the volume of the diamond is 137.1 cm³. The correct option is the last option 137.1 cm³

1) b.
2) a.
3) I'm not sure, but I'm leaning towards c.
<span>Let x=number of nickels in the piggy bank
(2x+3)=number of dimes in the piggy bank
(3x-3)=number of quarters in the piggy bank
.05x+.10(2x+3)+.25(3x-3)=14.55
.05x+.20x+.30+.75x-.75=14.55
</span>
<span>
1.00x=14.55+.45
x=15
2x+3=33
3x-3=42
The number of nickles in the piggy bank would be 15.
</span>
<span><span>The number of dimes in the piggy bank would be 33
</span></span>
<span>The number of quarters in the piggy bank would be 42. </span>
Hope I was able to help and that this was useful to you!!! :)
