Hello! The salary goes up 20% due to the promotion. His original salary was $20,000. To find out his new salary, you have to do is multiply the original price by the rate. 20,000 * 20% (0.2) is 4,000. His promotion is $4,000. Now, we add. 20,000 + 4,000 is 24,000. There. Perry's new salary is $24,000.
69.92 when you add them all up and divide it you get 69.92
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.
