Parabola remember that parabola equation is 4p(y-k) =(x-h)^2 for a verticl parabola p=distance from vertex to focus and from vertex to directix solve for p, k, h
y=0.6x^2
4p(y-0)=(x-0)^2 divide both sides by 4p (y-0)=1/4p times (x-0)^2 y=0.6x^2
1/(4p)=0.6 find p multiply 4p 1=2.4p divide 2.4 1/2.4=p h=0,k=0 vertex=0,0 opens up so go up to find focus (0,0) 0+1/2.4=1/2.4 focus is at (0,1/2.4)
when the angles make out a straight line it equals to 180 and 180 subtracted to 119 comes out to 61 and both b and c are vertical angles which would make them congruent
