The answer would be B. As you can see Angle A and angle B are connected by that line and together they would equal 90 degrees like on the other side of line AB.
Hello here is a solution : <span> the radius of the circle is OA A(5;-12) and O (0;0) OA= </span><span> square root ((5-0)² + (-12-0)²) </span> = <span> square root (25+144) </span> = <span> square root(169) </span> OA = 13
