Answer:
3524.4 g
Step-by-step explanation:
- Use formula: Density = Mass/Volume
- Mass= Density * Volume
Multiply 14 to each term: 14a+70+84b
<em><u>Complete Question:</u></em>
The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?
<em><u>Answer:</u></em>
The numerator of fraction is -360
<em><u>Solution:</u></em>
Given that,
<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>

We have to solve the equation for "n"
Rearrange the equation

Thus the numerator of the fraction is -360
