The sum is (n-2)180. N is the number of sides. In this case, you have 20 sides. You get (20-2)180, which is 18x180 and results in 3240 degrees. This is the sum!! To get one angle, do the same thing but divide it by 20. The formula, as seen in the question, is (n-2)180/n. Therefore, you have (20-2) 180 divided by the number of signs, which is 20. Since 18 times 180 = 3240 is the (n-2)180, divide 3240 by 20. You get 162° for each angle.

Answers

Answer:

25

Step-by-step explanation:

Given,

Measurement of <1 = x + 10

Measurement of <2 = 4x + 5

Also, said in the question that both these angles are complementary.

Therefore, by the problem,

<1 + <2 = 90°

=> x + 10 + 4x + 5 = 90

=> x + 4x + 10 + 5 = 90

=> 5x + 15 = 90

=> 5x = 90 - 15 = 75

[tex] = > x = \frac{75}{5} [/tex]

=> x = 15

Now, we have got the value of x so,

Measurement of <1 is

<1 = x + 10 = 15 + 10 = 25 (Ans)

An expression has a leading coefficient that is a perfect square is 49w²+4+53.

What is a perfect square?

A perfect square is a positive integer that is obtained by multiplying an integer by itself. In simple words, we can say that perfect squares are numbers that are the products of integers by themselves.

The term with the highest degree i.e., the term with the largest power of the variable is the leading term. The leading coefficient is the leading term's coefficient.

In the polynomial 49w²+4+53

The highest degree is with the term 49w² is 2, and its coefficient is 49.

49=7×7=7²

So, 49 is the perfect square.

a total of 420 tickets were sold for the school play. they were either adult tickets or student tickets. the number of students tickets sold was two times the numberof adult tickets sold. how many adult tickets were sold?​

Answers

108 adult tickets sold.

Explanation:

To do this equation, we can set x equal to the number of adult tickets sold, and then set up the following equation:

x+3x=432

Since there are three times as many student tickets as adult tickets and the total is 432, you can just use all this information together to make an equation. From there, you can combine like terms to create this equation:

4x=432

After this, just divide both sides by 4 to reach the answer of:

x=108
