A polygon has an interior angle sum of 2520 degrees. How many sides must the polygon have?

Mathematics

NISA [10]3 years ago

So since the formula for the sum of a polygon's interior angles is (n-2)180, just make that equal to 2520 and solve for n, which is the number of sides.

STEPS:

1) (n-2)180 = 2520

2) n-2 = 2520/180

3) n-2 = 14

4) n = 16

So the polygon must have 16 sides

Shaka and ajani playa a game shaka scores 30%of maximum points and misses the record by 15 points ajani gets 40% of maximum pint
stellarik [79]

Step-by-step explanation:

First, we should focus on their records and percents.

Shaka: 30%, -15 points.

Ajani: 40% +35 points.

When we subtract 35 and -15, we get the difference of 50.

We know 10% is 50 point difference, 20% is 100 point difference, 30% is 150 point difference, etc.

But that's not correct.

  • It has to be in the Negatives.
  • It cannot be positive under 30%.

Since 30% is -15 points, we subtract 50 for 20%, then another 50 for 10%.

Our Correct work is:

0% = -0, 10% = -115, 20% = -65, (30% = -15, 40% = 35.)

- We are correct.

Then, since we are correct, we keep going.

30% = -15, 40% = 35, 50% = 85, 60% = 135, 70% = 185, 80% = 235, 90% = 285, 100% (Or Maximum Point): 335.

Therefore, the Maximum Point is 335 points.

Best of Luck to you!

100 POINTS!!!! Please be quick and make sure you have a correct answer, no plagiarizing, and no silly answers. Will give BRAINLI
NikAS [45]

Part A

5x 3y^3 2z

I know it is in standard form because there are no more like terms.

Part B: Polynomials are always closed under multiplication. Unlike with addition and subtraction, both the coefficients and exponents can change. The variables and coefficients will automatically fit in a polynomial. When there are exponents in a multiplication problem, they are added, so they will also fit in a polynomial.
