Polygon abcd has sides with these lengths: , 5 units; , 4 units; , 4.5 units; and , 7 units. the slope of is 5, the slope of is 0.25, the slope of is -2, and the slope of is 0. the polygon is dilated from point a by a scale factor of 1.2 to form polygon a′b′c′d′. match the slopes and lengths of the sides of polygon a′b′c′d′ to their values.

Step-by-step explanation:

we know that

Polygon ABCD and Polygon A'B'C'D' are similar

therefore

The slopes of the sides of polygon ABCD are the same of the slopes of the sides of polygon A'B'C'D'

and

the measurements of the sides of polygon A'B'C'D' are equal to the measurements of the sides of polygon ABCD multiply by the scale factor

we have

so

Find the slopes of the dilated figure

Find the length sides of the dilated figure

Find the length side of C'D'

we have

substitute

Find the length side of A'D'

we have

substitute

x=30
