Answer:
6 sides
Step-by-step explanation:
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Let us represent:
Sum of Exterior angle as x
Sum of Interior angle as y
Note that:
The sum of the exterior angles of a polygon = 180 - The sum of the interior angles
Hence,
The sum of the exterior angles of a polygon + The sum of the interior angles = 180
x + y = 180
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles.
2x = y
Substituting
x + 2x = 180°
3x = 180°
x = 180/3
x = 60°
Solving for y
2x = y
2 × 60° = y
120° = y
Hence,
Sum of Exterior angle as x = 60°
Sum of Interior angle as y = 120°
The number of sides of a polygon is
360°÷ Sum of Exterior angles
= 360° ÷ 60
= 6 sides

Step-by-step explanation:
area of a trapizium is 84m².its pararrell sides are 12m and 9m. find its hiegh
Answer:
8m
Step-by-step explanation:
We can convert the trapezium into a rectangle to make finding the area easier.
Say that the top side is 9m, and that the bottom side is 12m.
12 - 9 = 3
3/2* = 1.5
*Note that we are dividing by two to get the "overhang" of the bottom side.
Now that we have our overhang, we can find the length of the "t-rect"**.
**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.
12 - 1.5 = 10.5
9 + 1.5 = 10.5
The length of the t-rect is 10.5.
84/10.5 = 8
The height of the t-rect is 8m.
Since the height of the original trapezium is equal to the height of the t-rect***,
***Since we have only adjusted the length
this also means that 8m would also be the height of the original trapezium.
Now, there is a second way of doing this.
Find the median of 12 and 9.
9, 10, 11, 12
10, 11
The median is 10.5.
84/10.5 = 8
You get the same answer. These methods could be used as a solve-then-check method to another problem like these.
Hope this helps. Have a nice day.

Aaliyah needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3 hours and charged her $66 for parts. The total was $441. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Equation:
Answer: x =
Answer:
x=125
Step-by-step explanation:
First identify what the varible means,
x = the cost of the labor per hour.
Next, write out an equation
3x + 66 = 441
Solve,
3x+66=441
Step 1: Subtract 66 from both sides.
3x+66−66=441−66
3x=375
Step 2: Divide both sides by 3.
3x/3 = 375/3
x=125
Juan sells 3 oranges for every 2 apples. How many apples should Juan expect to sell
when Juan sells 15 oranges:
Answer:
10 apples
Step-by-step explanation:
We can write a ratio to solve
3 oranges 15 oranges
--------------- = -----------------
2 apples x apples
Using cross products
3x = 2 * 15
3x = 30
Divide by 3 on each side
3x/3 = 30/3
x = 10
Answer:
He can expect to sell 10 apples
I don’t understand this
Answer:
so, for each of the questions you have to change the expression into slope intercept form, then use that equation to graph a line on the graph.
i'll help you out:
11. y= 3/2x+5 (0,5) (-4,2 )
12.y= -2x-5 (0,-5) (-1,-3)
13. y= -2x-3 (0,-3) (-1,-1)
14. y= x-4 (0,-4) (4,0)
Step-by-step explanation:
the first expression is the slope intercept form and the parenthesis are the points.
