h = 5 because if you added 8 to the other side of the equation, then the equation would be in vertex form, where the opposite of h, and the value of k (8) is your vertex. So, we know that the x-value of the vertex is also the axis of symmetry, so the axis of symmetry is also the x-value of the vertex, or h.
Hope this helps! :)

Step-by-step explanation:
Answer:
40º
Step-by-step explanation:
straight line: 180º
180-58-82=40
For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.
For
y=a(x-h)^2+k
the axis of symmetry is x=h
so
y=2/3(x-2)^2-5
the axis of symmetry is x=2
answer is C
