Answer:
Step-by-step explanation:
line given is x-y+1= 0
you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis
x-y+1 =0 subtract x and 1 from both sides of the equation
-y = -x-1 multiply both sides by -1
y = x+1 so the slope of this line is 1 and the y-intercept is 1
If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
The data is a little bit complex,but you can use the knowledge of vector in the subject of algebra,or you can ultimate the basic Euclidean knowledge,like cosine theorem.In detail,you can list two equation with two variable,and get the answer.but i don't finish calculating it.
15/8 is already an improper fraction, if you want a proper fraction the answer is 1 and 7/8
Step-by-step explanation:
The measure of CED is p degree.
In triangle ABC and EDC,(Given)(Vertical opposite angles)
By AA rule of similarity,
Corresponding angles of similar triangles are same.
Therefore the measure of CED is p degree.

Answer: The correct option is c.
Explanation:
Reason for correct option:
This expression cannot be factored further because 
is the complete factor. Therefore the option c is correct.
Reason for incorrect option:
Since the given expression can be factored further therefore the option d is incorrect.
Since the given expression can be factored further. Therefore the option a is incorrect.
Since the given expression can be factored further. Therefore the option b is incorrect.
