<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
-10 + a = 6a - 7a
Rearrange the left hand side
a - 10 = 6a - 7a
Simplify 6a - 7a
a - 10 = -a
Add a on both sides
2a - 10 = 0
Add 10 on both sides
2a = 10
Divide by 2 on both sides
a = 5
Answer:
Step-by-step explanation:
given is a function as

We are to find the area form x=1 to x=t
The curve from x=1 lies in the I quadratnt.
So area above x axis is to be calculated
Area = 
a) When t =10,
area = 
b) t=100
area = 
c) t=10000
area = 
Answer: Option A
Explanation: The lights that is incident on a mirror will be reflected back as it is a smooth surface and it reflects back the light.
the light will be reflected by the same angle as it was incidented. The angle of incidence can be defined as the angle by which the light ray falls on the surface of the mirror.
The angle by which the light reflects back is known as the angle of reflection. Being a smooth surface light ray is reflected back.
