Answer: 147 Degrees
Step-by-step explanation
The size of the final unknown interior angle in a polygon is 147 degrees.
Given that,
The other interior angles are 162°, 115°, 120°, 148° and 85°.
We assume that there is an equation (2n - 4) 90.
Here n be 7.
Based on the above information, the calculation is as follows:
= (2n - 4) 90
= ((2) (7) - 4) 90
= 10 (90)
= 900
Now the size of the unknown interior angle is
= 900-(162+125+148+105+98+115)
= 900 - 753
= 147°
Therefore we can conclude that the size of the final unknown interior angle in a polygon is 147 degrees.

To solve for x you do these steps
x=number
1. do this following multiplication problem to get 0.9%
36/x*100%= 0.9%
2. now do the opposite of what you did before to get x
36 divided by 0.9%= x
36 divided by 0.9%= 40
x = 40
Answer:
See Below.
Step-by-step explanation:
We are given the function:
And we want to show that it has at least one zero between <em>x</em> = 1 and <em>x</em> = 2.
Because the function is a polynomial, it is everywhere continuous.
Evaluate the function at <em>x</em> = 1 and <em>x</em> = 2:
And:
Therefore, because the function changes signs from <em>x</em> = 1 to <em>x</em> = 2 and is continuous on the interval [1, 2], by the intermediate value theorem, there must exist at least one zero in the interval.
The solution to the given linear equation is x=1
<h3>Solution to linear equation</h3>
Linear equations are equations that has a leading degree of 1.
Given the linear equation as shown below;
8x - 5= 2x + 1
Subtract 2x from both sides
8x - 2x - 5 = 2x + 1-2x
6x - 5 = 1
Add 5 to both sides
6x - 5 + 5 = 5 + 1
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
Hence the solution to the given linear equation is x=1
