Answer:  
<u>Step-by-step explanation:</u>
Pythagorean Theorem is: a² + b² = c²   , <em>where "c" is the hypotenuse</em>
<em />

Note: 4² + (8√2)² = hypotenuse²   →   hypotenuse = 12

Note: 12² + opposite² = 20²   →   opposite = 16

Note: adjacent² + 5² = 6²   →   adjacent = √11

Note: adjacent² + 7² = (13√2)²   →   adjacent = 17

Step-by-step explanation:
 
        
             
        
        
        
We have
y²=-12x
the vertex is the point (0,0)------------- > see the attached figure
<span>
standard form: (y-k)^2=4p(x-h), with (h,k) being the (x,y) coordinates of the vertex.
vertex(0,0) 
4p=-12---- > p=-12/4
p=-3
Focus:(-3,0)
</span>the answer is (-3,0)
