Step-by-step explanation:
measure of exterior angle = sum of 2 non adjacent angles
4X = 90 + X
3X = go
X=30
exterior angle = 30x 4 =120
Answer:
The vertex: 
The vertical intercept is: 
The coordinates of the two intercepts of the parabola are
and 
Step-by-step explanation:
To find the vertex of the parabola
you need to:
1. Find the coefficients <em>a</em>, <em>b</em>, and <em>c </em>of the parabola equation
<em>
</em>
2. You can apply this formula to find x-coordinate of the vertex
, so

3. To find the y-coordinate of the vertex you use the parabola equation and x-coordinate of the vertex (
)

To find the vertical intercept you need to evaluate x = 0 into the parabola equation

To find the coordinates of the two intercepts of the parabola you need to solve the parabola by completing the square
