Answer:
The answer to your question is Ф = 45°
Step-by-step explanation:
Data
A (1, 4)
B (-1, 2)
Process
1.- Find the slope of the line
formula
m = 
Substitution
m = 
Slope definition, is the steepness of a line and also is the tangent of the angle of the line.
tangent Ф = slope
tangent Ф = 1
Ф = tangent⁻¹ 1
Ф = 45°
Isn’t this just 20m? Or is it a trick question and I’m just not getting it?

Answer:
Option 1
Step-by-step explanation:
Remember that range is the x values or the input. So in this case the inputs {0, 1, 2, 3} are all matching the ones in option one!
Hope this helps and have a great day!
Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
- DC=DE
- DF is a common side
So, the two triangles are congruent. It follows that CF=FE, and in particular
And since x=3, the length of EF is
