In the figure. What is the value of x? Also it cropped out the last answer choice which is 90.
1 answer:
So hmm notice the picture below
I've included the "far arc - near arc" equation to get the angle made by both tangents
now, if we make k = x, which is your case
and we make the "near arc" to "x", which is also the case
and then we make the "far arc" to say "b"
so using the "far arc - near arc" equation, we get that

Answer:
The center is of the whole target.
Step-by-step explanation:
Given:
Diameter of the center = 5 inches
Diameter of the whole target = 25 inches
We need to find the part of the center to the whole target.
Solution,
Firstly we will find out the areas of center and whole target.
For center;
Diameter = 5 in
Radius of circle is equal to half of the diameter.
radius =
Now we know that the area of circle is equal to π times square of the radius.
framing in equation form, we get;
Area =
For whole target;
Diameter = 25 in
Radius of circle is equal to half of the diameter.
radius =
Now we know that the area of circle is equal to π times square of the radius.
framing in equation form, we get;
Area =
Now to find the part of the center to the whole target we will divide Area of center with Area of the target.
framing in equation form we get;
the part of the center to the whole target =
Hence the center is of the whole target.
