Step-by-step explanation:
For a polygon of n sides, the sum of the measures of the interior angles is
(n - 2)180.
A quadrilateral has 4 sides, so n = 4.
(4 - 2)(180) = 2(180) = 360
Answer: 360 degrees.

Answers
Answer:
I guess that we have the equation:
(1/3)^2 + 3^2 =
And we want to solve it.
Here just remember that:
3^2 = 3*3 = 9
then:
(1/3)^2 = (1/3)*(1/3) = 1/9
replacing these in the expression, we get:
(1/3)^2 + 3^2 = 1/9 + 9
If we want to write this as a single fraction, we can rewrite:
1/9 + 9 = 1/9 + (9/9)*9
= 1/9 + 81/9 = (1 + 81)/9 = 82/9
The solution to the equation is 82/9. The equation is: [tex](1/3)^2 + 3^2.[/tex]Calculate the square of [tex](1/3): (1/3)^2 = 1/9[/tex]
Calculate 3 squared:
[tex]3^2 = 9[/tex]
Now, substitute these values back into the original equation:
[tex](1/3)^2 + 3^2 = 1/9 + 9[/tex]
To add these fractions, you need a common denominator. In this case, the common denominator is 9:
1/9 + 81/9 = (1 + 81)/9 = 82/9
So, the solution to the equation is 82/9.

Can someone please help me
Answers
Answer:
A x >= 0
Step-by-step explanation:
a function is a defined mathematical operation (or a sequence of operations) that uses input values (typically called "x") and calculates the corresponding results (typically called "y").
so, y = f(x)
and (x,y) are then usually the coordinates on the grid.
the domain is the range or interval of numbers the function is using (x) to create results (y).
so, look at the graph !
for what values of x do you see the functional line drawn ?
that means, the functional line goes along only what part of the x-axis ?
I see it starts at x=0 and then continues all the way to the right and clearly further.
for me that means f(x) calculates values for every positive x we can think of. and including 0.
it does not do anything for any negative x-values.
so, clearly answer A (x>=0) is right.

simplify
47/13 = 3.677
We now have 3.677 = RS/6
Multiply each side by 6
3.677 * 6 = 22.1
RS/6 * 6 = RS

x = 9
Step-by-step explanation:
Given 2 secants from an external point to the circle , then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
3(3 + x) = 4(4 + 5) ← distribute parenthesis on both sides
9 + 3x = 16 + 20 = 36 ( subtract 9 from both sides )
3x = 27 ( divide both sides by 3 )
x = 9

Answers
Answer:
x = 15.8
Step-by-step explanation:
let the number be x
according to the question equation is
x*5 - 2 = 77
5x - 2 = 17
5x = 77 + 2
5x = 79
x = 79/5
x = 15.8
Answer:
5x - 2 = 77
x = 15.8
Step-by-step explanation:
a number - x
times 5 - 5x
minus 2 - 5x - 2
equals 77 - 5x - 2 = 77
77 + 2 = 79
79 ÷ 5 = 15.8
5(15.8) - 2 = 77

2x = 72
x = 36
x + 14 = 50
