We need to convert the equation of the circle to standard form only then we can find the radius and the center of the circle.

From this equation we can write:
Center of the circle is (-1,1) and the radius of the circle is 4.
(1) QS bisecting <PQR implies <PQS = <SQR
(2) <PQS=45 deg and (1) imply <SQR also = 45 deg
(3) from (2) it follows that <PQR = <PQS + <SQR = 45 + 45 deg = 90 deg and therefore the triangle is right-angled
The first question I think it’s A because 1.13 is larger than 1.2
