Answer:
D ; 0
Step-by-step explanation:
Answer:
y = -x + 8
Step-by-step explanation:
First, plug in the slope.
y = mx + b
y = -1x + b
y = -x + b
Then, plug in the point.
7 = -(1) + b
7 = -1 + b
8 = b
Answer:

Step-by-step explanation:
Angle A and angle E are the same value, therefore you could replace angle E with angle A. So that would make a triangle with angle C, angle D, and angle A. Knowing the sum of all angles in a triangle is 180, we can make an equation representing this.

Now simply silve the equation to find x.

There is your answer.
Length=x
A=lengthxwidth
A=lengthx12
A/12= length
