A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.

8 sided regular polygon with one angle labeled 3 times x minus 15

Determine the value of x.

x = 40
x = 65
x = 50
x = 135

Answers

Answer:

x = 50

Step-by-step explanation:

The interior angle at each vertex of regular octagons are 135°.

3(50) - 15 = 135

For the polygon to be an 8 sided regular polygon like you said, the angle must equal 135, and so x must equal 50.

The required value of the x in the given expression is 50°.

Given that,
A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.

What is a polygon?

A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of polygons, equilateral triangles, squares, pentagons, etc

Here,
For the octagon,
The angle of a vertex is 135°.
Equating the angles,
3x  -15 = 135
3x = 135 + 15
3x = 150
x = 50

Thus, the required value of the x in the given expression is 50°.

The perimeter of a rectangular swimming pool is 154m. Its length is 2m more than twice its breadth. What is the length and breadth of the pool?

Answers

Let:
P be the perimeter of the pool
L = length of the pool
B = breadth of the pool

Given
======

P = 2L + 2B = 154 m
L = 2 + 2B

P = 2(2 + 2B) + 2B ……. Substitute
154 = 4 + 4B + 2B ……. Distribution
154 = 4 + 6B ……… Add like terms
154 - 4 = 6B
150 = 6B

150/6 = 6B/6 …….. Divide both sides by 6

25 = B …. Breadth

L = 2 + 2B
L = 2 + 2(25) = 2 + 50
L = 52

The result of the simplified expression in this problem is given as follows:

D. 15.

How to simplify the expression?

The expression for this problem is defined as follows:

2³ + 6/3 - (-10/2)

The parenthesis takes precedence, hence:

2³ + 6/3 - (-5) = 2³ + 6/3 + 5

The power takes precedence, hence:

8 + 6/3 + 5

Division has higher precedence than addition, hence:

8 + 2 + 5.

Hence the result is given as follows:

8 + 2 + 5 = 15.

Some people advise that in freezing​ weather, you should keep the gas tank in your car more than half full. ​Irene's car had Irene 5.7 gallons in the ​13-gallon tank on the coldest day of the year. filled the tank with gas that cost ​$3.80 per gallon. How much did Irene spend on​ gas?

Answers

Some of the information here isn’t needed, like that fact that it’s freezing and that the tank holds 13 gallons. If gas costs $3.80 per gallon, then 5.7 gallons would cost $27.66

It’s 27.74. We take 13-5.7 which is 7.3. Then we multiply 7.3x3.80 which is 27.74.

You need to find out how big the backyard is first by multiplying both lengths.
