What is the measure of an exterior angle in a regular polygon with 12 sides

Mathematics
1 answer:
Snezhnost [94]3 years ago
6 0

Answer:

30°

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Since the polygon is regular then

exterior angle = \frac{360}{12} = 30°

Find the location of G, the midpoint of FH.
Ede4ka [16]

The coordinate of G is (3,6.5).

<h3>What is Section Formula?</h3>

When a point on a line segment divides it into two segments, the formula used to determine the coordinates of that point is known as the section formula.

The Coordinate of F is (1, 7)

The Coordinate of H is (5,6)

Since G is the midpoint. So, it divides the line FH in 1:1 part

Let coordinates of G be (x, y)

Now using Section Formula,

x= \frac{1*1+1*5}{2} \;\;\; and \;y= \frac{1*7+1*6}{2}

x= 3 and y = 6.5

Hence the coordinate of G is (3,6.5)

1, 3, 6, 10, 15 is it arithmetic, geometric or neither
Gekata [30.6K]

The given sequence is neither arithmetic nor geometric.

Further explanation:

In order to check whether a sequence is geometric or arithmetic we have to find the common ratio and common difference respectively

Common difference is the deifference between cunsecutive terms of a sequence while common ratio is the ratio between two consecutive terms.

Common difference is denoted by d and common ratio is denoted by r

  • If the common difference is same then the given sequence is an arithmetic sequence
  • If the common ratio is same then the given sequence is a geometric sequence

Given

1, 3, 6, 10, 15

Common difference:

Here

a_1=1\\a_2=3\\a_3=6\\a_4=10\\a_5=15\\Common\ Difference=a_2-a_1=3-1=2\\a_3-a_2=6-3=3\\a_4-a_3=10-6=4

As the common difference is not same, the given sequence is not an arithmetic sequence

Common Ratio:

r=\frac{a_2}{a_1}=\frac{3}{1}=3\\\frac{a_3}{a_2}=\frac{6}{3}=2\\\frac{a_4}{a_3}=\frac{10}{6}=1.6

As the common ratio is also not same the sequence is not a geometric sequence.

The given sequence is neither arithmetic nor geometric.

Keywords: Arithmetic sequence, Geometric Sequence

Dividir 254 en tres partes tales que la segundasea el triplo de la primera y 40 unidades mayor que la tercera
Gelneren [198K]

Responder:

x = 40

y = 120

z = 80

Explicación paso a paso:

Número dividido = 240

Las 3 partes:

x, y, z

y = 3x

Z = 3x - 40

x + y + z = 240

x + 3x + 3x - 40 = 240

7x - 40 = 240

7x = 240 + 40

7x = 280

x = 280/7

x = 40

y = 3 (40)

y = 120

z = 3x - 40

z = 3 (40) - 40

z = 120 - 40

z = 80

Find the product of 2/3x4/7x14/5
Luden [163]
To multiply fractions, the numerator of the product is the product of the numerators, likewise for the denominators. (2/3) x (4/7) x (14/5) = (2 x 4 x14) / (3 x 7 x 5) = (112) / (105) = 1 and 1/15 .
