Answer:
The value of n is 21.
Step-by-step explanation:
We are given that three of the exterior angle of the n-sided polygon are 50° each two of its interior angle are 127° and 135° and the remaining interior angle are 173 each.
As we know that the sum of all exterior angles of the polygon is 360°. Also, the number of remaining interior angles will be (n - 5).
And, the exterior angle = 180° - the interior angle.
So, according to the question;
150 + 53 + 45 + 7(n - 5) = 360
248 + 7n - 35 = 360
213 + 7n = 360
7n = 360 - 213
7n = 147
n = 
n = 21
Hence, the value of n is 21 and this is a 21-sided polygon.
Answer:
The owner says that she will work 12 hours more than you if you get the job.
We know that she works 50 hours each week.
then, knowing that she works 50 hours per week and that she works 12 hours more than you, you have that, if H is the number of hours that you work per week, you have:
H + 12 = 50
Here says that the number of hours that you work, plus 12 hours, is equal to the number of hours that the owner works.
H = 50 - 12 = 38
This means that you would work 38 hours per week.
Answer:
The markup for the shoes is 20 percent.
Step-by-step explanation:
Answer:
+ 5°
Step-by-step explanation:
Given,
Good morning temperature = -15°
Raise in temperature = 20°
Afternoon temperature = -15° + 20°
= + 5°
Hence, temperature in after noon is equal to + 5°.
