Find the measure of one interior angle in each regular polygon. Plz
Answer:
108°
Step-by-step explanation:
If regular polygon has n sides, then each interior angle = 180° - (360/n)°.
When n = 5, interior angle = 180° - (360/5)° = 108°

The measures of two sides of a triangle are 4in and 13in. Find all possible values that the third side of this triangle can be?
Answer:
9 < x < 17 is the possible length of the third side of a triangle.
Step-by-step explanation:
The Triangle Inequality theorem defines that if we are given two sides of a triangle, the sum of any two given sides of a triangle must be greater than the measure of the 3rd side.
Given the two sides of the triangle
4 in13 inLet 'x' be the length of 3rd size.
According to the Triangle Inequality theorem,
The difference of two sides < x < The sum of two sides
13 - 4 < x < 13+4
9 < x < 17
Therefore, 9 < x < 17 is the possible length of the third side of a triangle.

. Brian can pick forty-five pounds of strawberries in six hours. If he works two ten-hour days, how many pounds of strawberries will he be able to pick?
Answer:
over 120 i think
Step-by-step explanation:
1. this is the first way to do it: because if he can pick 40 pounds in 6 hours and he worked for about 20 hours that if you divide 20 by 6 you will get three because 6x3=18 hours and 40x3= 120
2. the second way is when you subtrat 6-10 and get 4 leftover and if you do that twice you get 8 leftover in all and if you do 8-6 it is 2 leftover so in all you have you have three six hours out of 20 and so you would have to multiply 40 times 3 because every six is 40 pounds of strawberries.

find the value of x. inscribed angles
9514 1404 393
Answer:
x = 33°
Step-by-step explanation:
The value of an inscribed angle is half the value of the arc it subtends.
The angle marked x subtends the arc marked 66°, so has a value of ...
x = 66°/2
x = 33°
_____
The value of y is similarly found.
y = 96°/2
y = 48°
__
The angle marked with a dot is an external angle of the triangle, so is the sum of the remote internal angles, x and y:
dot angle = x + y = 33° +48° = 81°
Of course, angle z is the supplement of this:
z = 180° -81°
z = 99°
Answer:
x=33
Step-by-step explanation:
The answer would be x=33

Anybody know this? I need some help
Answer:
17
Step-by-step explanation:
First, you can change the equation to 12 1/2 + 4 1/2, as subtracting a negative number is actually adding it. Then, if easier, the mixed numbers can be changed to improper fractions -- 12 1/2 = 25/2 and 4 1/2 = 9/2. Then add; 25/2 + 9/2 = 34/2, and 34 divided by 2 is 17.

A TV is measured by its diagonal. If the height of a 60 inch
TV is 32 inches, what is the width?
Given :
A T.V. is measure by its diagonal.
To Find :
If the height of a 60 inch T.V. is 32 inches, what is the width.
Solution :
We know, T.V. is rectangular in shape and angle between two sides of rectangular is 90° .
Let, width of T.V. is x.
Applying Pythagoras theorem in sides, we get :
[tex]height^2 + width^2 = hypotenuse^2\\\\23^2 + x^2 = 60^2\\\\x = \sqrt{3600 -529 }\\\\x = 55.42 \ inches[/tex]
Therefore, width of T.V. is 55.42 inches.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
2x/3 ÷ 3x/2 when x ≠ 0.
This can be written as,
= (2x/3) x (2/3x)
= 2/3 x 2/3
= 4/9

out. The length of the garden is 8 feet more than the width. If the perimeter
of the garden is 308 feet, what is the length and the width?
Answer:

teresa says the two expressions below are equivalent: 2(5x-3) + 6x and 16x -3 is teresa correct? Explain why or why not
Answer:
No.
Step-by-step explanation:
2(5x-3) + 6x is equal to 16x-6:
Distribute:
=(2)(5x)+(2)(−3)+6x
=10x+−6+6x
Combine Like Terms:
=10x+−6+6x
=(10x+6x)+(−6)
=16x+−6,
Which is not equal to 16x-3
