formula for interior angles of a polygon is 180 times the number of sides minus 2
20 a 20gon has 20 sides, 20 -2 = 18, 180*18 = 3240
sum of interior angles = 3240 degrees

Answer:
Option C is the correct answer.
C. 5•(-20)
Step-by-step explanation:
We are told that the insurance payment for the car follows a certain pattern that can be represented through an expression. The payment is decreasing by $20 every year. As we don't know the total payment amount per period, so we cannot calculate how much is paid per period/year for insurance but we can calculate the rate at which this payment is decreasing.
Change in payment = t * (-20)
The above expressions can be used to calculate the amount of change in payment i payment is decreasing by a constant $20 every year, after t years.
So, if we want to calculate the change in payment after say 5 years, we can replace t with 5 in the equation and calculate the change,
Change in payment = 5 * (-20)
Change in payment = - $100
Answer:
5:3
Step-by-step explanation:
to simplify this equation we have to find something that both numbers can be divided by
both numbers can be divided by 7
so when we divide the numbers we get
5b = 3c
so basically the ratio is 5:3
