Answer:

Step-by-step explanation:
The vertex of this parabola is the midpoint of the focus (-2,4) and where the directrix intersects the axis of symmetry of the parabola (-2,6)
This parabola must open downwards due to the position of the directrix and has equation of the form:

where (h,k) is the vertex.
This implies that:

and

The value of p is the distance from the vertex to the focus:

We substitute all the values into the formula to get:


Or

Answer:
x = 26
Step-by-step explanation:
The sum of the angles around point O = 360°, thus
x + 3x + 256 = 360 , that is
4x + 256 = 360 ( subtract 256 from both sides )
4x = 104 ( divide both sides by 4 )
x = 26
Exact form:
22/13
Mixed number:
1 9/13
