<em>x = 25</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
- <em><u>
the opposite angles are equal</u></em>
<em><u>4x - 25 = 25 + 2x</u></em>
<em><u>4x - 2x = 25 + 25</u></em>
<em><u>2x = 50</u></em>
<em><u>x = 50 : 2</u></em>
<em><u>x = 25</u></em>
<em><u>Good luck ! </u></em>
Answer: The center is 0,4
Step-by-step explanation:
Use this form to determine the center and radius of the circle:
(
x-h)^2+(y-k)^2=r^2
Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin:
r=8
h=0
k=4
The center of the cirle is found at (h,k): (0,4)
The radius is 8
