Add the equations to eliminate p. That leaves w open to solve.
C is correct. You have to pay attention to the corresponding sequences of the vertices. C is correct because in the three triangles, MON, MPO, OPN are the right angles, respectively. However, the angles are not consistent in other given choices.
General form of circle with center at C(a,b) and radius r is
(x-a)^2 + (y-b)^2 = r^2. Here,
(x-(-3))^2 + (y-12)^2 = 5^2, or (x+3)^2 + (y-12)^2 = 25
Answer:
.5 and .5, .75 and .25, ect
