Determine the general form of the equation for the circle x2 + (y + 1)2 = 2. x2 + y2 + 2y = 3 x2 + y2 + 2y + 3 = 0 x2 + y2 + 2y – 1 = 0 x2 + y2 + y – 1 = 0

Alex drew a circle with right triangle prq inscribed in it, as shown below: the figure shows a circle with points p, q, and r on it forming an inscribed triangle. side pq is a chord through the center and angle r is a right angle. arc qr measures 80 degrees.

Can someone check if i did this correct. it’s number 4 if you’re wondering.
