Answer:

Step-by-step explanation:
We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).
Note that x=1 is a <em>vertical line </em>since x is 1 no matter what y is.
This means that if our new line is perpendicular to the old, then it must be a <em>horizontal line</em>.
So, since we have a horizontal line, then our equation must be our y-value of our point.
Our y-coordinate of our point (8,-9) is -9.
Therefore, our equation is:

And this is in standard form.
And we're done!
<h2><u>79 degrees</u> is the correct answer!</h2><h3></h3><h3>Line PU is <u>supplementary.</u></h3><h3>30 + 34 + 37 = 101</h3><h3>180 - 101 = <u>79</u></h3><h3><u /></h3><h3>I want to be marked "brainless."</h3><h3>I want to be a zombie.</h3><h3>lm-ao</h3><h3 /><h3><em>Please let me know if I am wrong.</em></h3>
If x is any given number than I will use the Number five
Your equation will look like this
5^5=25
answer is 1.566 deg
Step-by-step explanation:
The angle of elevation is given by the formula
tanθ = height/distance
tanθ = H/ 240
tanθ × 240 = H
θ =( tan∧-1) 240
= <u>1.566 deg</u>
Given:
Radius of small circle = 4 in.
Width of gray border = 2 in.
To find:
The area of the gray border.
Solution:
We have, radius of small circle:

The width of gray border is 2 in. So,t he radius of the larger circle is:


Now, area of gray border is the difference for area of larger circle and smaller circle.


Substituting
in the above formula, we get




The area of the gray border is
square inches. Therefore, the correct option is D.
