Find the measure of each interior angle and each exterior angle of a regular 90-gon.

Answers

Answer 1

Answer:

Interior angle

176 degrees

Exterior

4 degrees

Step-by-step explanation:

Exterior angle

For any polygon, the measure of the total exterior angle is 360

To get the individual exterior angle, we divide the total by n, which is the number of sides, 90 in this case

We have this as;

360/90 = 4

Interior

To get the measure of each interior angle, we use the formula below;

[(n-2)180]/n

n in this case is 90

So we have

[(90-2)180]/90

= (88 * 180)/90

= 2 * 88 = 176

what is the side length of a square given the area to be 625m

Answers

Answer: 25 meters

Step-by-step explanation:

✓625 = 25

Answer:25

Step-by-step explanation:A square has equal length on all its sides, so the area of square is

Length x Length = 625

Which is

Length ^2 = 625

We want the number that when it times it’s self it’s 625

It can be done by square root of 625 which is 25. So the length of side is 25.

Or look at the prime factorization of 625 ( or just factors) and what number they can make up

Which is 5x5x5x5 = 625

They can make up

5^2 x 5^2 = 25 x 25 that is the “same” number

So the length is 25

what is the linear equation of a line with a rate of change of -1/2 that passes through the point (0, 4)

Answers

Answer:

y = 9/2 (fraction)

Step-by-step explanation:

y = mx+c

m = slope

c =y -intercept

Therefore, the required equation is:

y = 2x + c

Putting the point (0,4) in it as it lies on a line, we get:

4 = -1/2 + c

Therefore:

c = 9/2

So, y = 9/2

Which of the expressions below has a 1 in the tenths place of the product? Select all that apply. A) 18.3 x 7 B) 6.5 x 4.31 C) 8.54 x 2.3 D) 5.4 x 2.8

Answers

Answer: A) 18.3 x 7 and D) 5.4 x 2.8

Step-by-step explanation:

A) 18.3 x 7 = 128.10

We can infer that 1 is in the tenths place.

B) 6.5 x 4.31 = 28.015

We can infer that 1 is not in the tenths place but rather the hundredths place.

C) 8.54 x 2.3 = 19.642

We can infer that 1 is not in the tenths place.

D) 5.4 x 2.8 = 15.12

We can infer that 1 is in the tenths place.

Answer:

1. The radius of the circle is 6cm. We know this because the radius measures from the center of a circle to the outer side. Since the radius is always half the diameter then half of 12cm is 6cm

2. The diameter is 14cm. We know this because diameter measures from one edge of a circle straight across to the other side. Also the radius is always half the diameter so 7cm*2=14cm

Answer:

g(3) is -12

Step-by-step explanation:

Given that

g(1)= -2

g(2)= 6

g(n)=g(n−2)⋅g(n−1)​

Now the g(3) is

g(3) = g(3 - 2) . g(3 - 1)

= g(1).g(2)

= (-2) (6)

= -12

Hence, g(3) is -12
