I'm not too sure on this can i have some help
Ganezh [65]
Welcome to Brainly. We are here to help! 

Similar polygons vary directly with each other. They have the same scale.

Something I notice about the polygons is that both of the sides are decreased by 10.

40-30= 10 and 28-18=10

Try to find the scale.

40/28= 1.42857....

30/18= 1.666666777


I would say these are not similar polygons. They do not share the same scale.

I hope this helps!

What is the slope of a line that is perpendicular to the line represented by the equation y-5x=5?
zalisa [80]
Perpendicular lines have negative reciprocal slop to each other.
So first solve for y.
Slope will be the coefficient of x in y=mx+c form.
m is the slope. Then negative reciprocal this slope and in this case the answer is -1/5
