Answer:

x = 6

Step-by-step explanation:

The three angles form a straight line, which is 180 degrees

5x+ (x+54) +90= 180

Combine like terms

6x+144 = 180

Subtract 144 from each side

6x+144-144 =180-144

6x =36

Divide each side by 6

6x/6 = 36/6

x = 6

An equation of a parabola with its vertex at (-3,2) and focus at (-3,-1) written in general equation form

german

we have that
standard form of equation for parabola:
(x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)

the answer is (x+3)^2=-12(y-2)
