It’s not exactly equal to one, but in many cases in math they ask for a rounded answer.
Not quite sure what this is
The answer is B because it is 7 zeros behind the decimal and when you swoop 8 times left, you get 0.0000000398.
Step-by-step explanation:
x + 107 + 34 = 180
x + 141 = 180
x. = 180 - 141
x = 39
the above method can be used if the angles are the interior angles of triangle or for all angles in a straight line .
- Center =
- Radius =
<u>Step-by-step explanation:</u>
Here we have following equation :
We need to find the center & radius of this circle . Let's find out:
We know that , Equation of a circle is given by :
⇒ ........(1)
Here , (h,k) are the co-ordinates of center & r is the radius of circle.Collectively called as a circle with radius r and center at (h,k) . Let's frame given equation in question :
⇒
⇒
On comparing this equation with equation (1) we get :
- Center =
- Radius =
