Polygon r and polygon s are similar. the perimeter of polygon r is 72 cm, and the perimeter of polygon s is 36 cm. if one side of polygon s is 6 cm, what is the length of the corresponding side in polygon r? a. 3 cm b. 12 cm c. 36 cm d.6 cm

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
