Answer:
m< 2= 95
m< 3= 85
m< 4= 95
Step-by-step explanation:
All adjacent angles are the same, making m< 3 85. 85 + 85 = 170. Because all of it is equal to 360 (a circle) subtract 360 by 170. Than m<4 and m< 2 both need to split it so you than divide 190 by 2 and get 95.
This is one way of doing it.
We want to get the function into vertex form.
y = x2 - 4x + 2 Subtract 2 from both sides.
y - 2 = x2 - 4x Add (-4/2)2 , or 4, to both sides.
y - 2 + 4 = x2 - 4x + 4 Now that the right hand side is a perfect square trinomial, factor it.
y + 2 = (x - 2)(x - 2)
y + 2 = (x - 2)2 Subtract 2 from both sides.
y = (x - 2)2 - 2
When the equation is in this form, we can see that this is the graph of y = x2 shifted to the right 2 units and shifted down 2 units. The vertex is at (2, -2). So plot the first point at (2, -2) and go up just like a basic parabola from there. :)
