Answer:
X= -5
Step-by-step explanation:
y varies directly with x,
so y=kx
-34=k×2
k= -17
85= -17× X
X= -5
I think it might be 90 degrees
If the bigger pentagon has side length of 5 units and the smaller pentagon has side length of 1 unit, you can know that the dilation was 1/5 = 0.2
This means that the sides of the big pentagon were multiplied by 0.2 to obtain the smaller pentagon.
Answer:

Step-by-step explanation:
Write down the slope-intercept form:

Where m is the slope and b is the y-intercept.
To turn the equation into slope-intercept form, isolate y on the left-hand side:

Rearrange the equation a bit:
