O A. x²-7=7
B. x2 + y2 = 49
c. x2 - y2 = 49
D. x² + 7 = 7

HELPPP ASAPPP

x^2 +y^2 = 49

Step-by-step explanation:

The equation for a circle is

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center of the circle and r is the radius

( x-0)^2 + (y-0)^2 = 7^2

x^2 +y^2 = 49

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.
