Answer:

a) 36°

b ) 18°

Step-by-step explanation:

The formula is given as:

The measure of each exterior angle =360°/n, where n = number of sides of a polygon.

a) decagon

Decagon = 10 sides

Hence, the measure of each exterior angle = 360°/10

= 36°

b) 20-gon

20-gon = 20 sides

Hence, the measure of each exterior angle = 360°/20

= 18°

horrorfan [7]

Answer:The number of words that she would still have to type to finish her essay is 1000

Step-by-step explanation:

Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be

4000/30 = 133.33 minutes.

If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be

45 × 30 = 1350 words

If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be

55 × 30 = 1650 words

Total number of words typed on Monday and Tuesday would be

1350 + 1650 = 3000 words

The number of words that she would still have to type to finish her essay would be

4000 - 3000 = 1000 words

You are having a discussion about sequences with your classmate. She insists that the sequence 2, 3, 5, 8, 12 must be either ari
Marizza181 [45]
If arithmetic, then there is a common difference
if geometric, then there is a common ratio

to find the common ratio or difference

if you subtract successive terms from each other, they should have the same result if it is aritmetic
if you divide successive terms by each other, they should have the same result if it is geometric


2,3 and 5

3-2=1
5-3=2
2≠1
not aritmetic

3/2=1.5
5/3=1.66666
1.5≠1.6666
not geometric

The length of one leg of a right triangle is 24 feet and the length of the hypotenuse is 40 ft what is the length of the other l
Rama09 [41]
To solve for the other leg, you need to use Pythagorean theory.

The theory states that C^2 = A^2 + B^2

In your case, you have to solve for B.
C = 40 (hypotenuse)   A = 24 (leg 1)

The formula rewritten for B is b= \sqrt{c^{2}-a^{2} }

Now, you can solve.

b= \sqrt{c^{2}-a^{2} }

b= \sqrt{40^{2}-24^2 }

b = \sqrt{1600 - 576}

b = \sqrt{1024}

b = 32

Therefore, B = 32.

So the second leg is 32 feet.
