8+(-2) =6
So the answer is 6
3 3/4 miles, because 6*5=30, so 30/8= 3 6/8, which equals 3 3/4 miles.
The angel in the scaled copy that corresponds to angle abc in the polygon pqrs which is a scaled copy of abcd will be angle pqr.
We have,
As we can see the attached figure,
Scale factor : Scale Factor is the ratio of size of new image formed to the size of old image and the image obtained is the scaled copy.
i.e.,
Scale factor = 
So,
There are two Polygons abcd and pqrs,
And,
Polygon pqrs is the scaled copy of Polygon abcd,
So,
That means both polygons are similar,
so,
Their corresponding angles will be same,
So
We can say that angle corresponds to angle abc is angle pqr.
Hence, we can say that the angel in the scaled copy that corresponds to angle abc in the polygon pqrs which is a scaled copy of abcd will be angle pqr.

180
The exterior angle of a triangle + the adjacent interior angle are supplementary, that is sum to 180°, thus
the exterior angle = 180 - adjacent interior angle
The radius and the center of the circle are 4 units and (1,2), respectively
<h3>How to determine the center and the radius?</h3>
The center of the circle is on
y = 2x and x = 1
Substitute x = 1 in y = 2x
y = 2 * 1
Evaluate
y = 2
This means that the center is
Center = (1, 2)
Also, we have the point of tangency to be:
(x, y) = (1, 6)
This point and the center have the same x-coordinate.
So, the distance between this point and the center is
d = 6 - 2
d = 4
This represents the radius
Hence, the radius and the center of the circle are 4 units and (1,2), respectively
