Polygon ABCD is similar to polygon WXYZ, and AB and wx are corresponding sides. You know the perimeter of each polygon, and you knowthe measure of BC. What can you find?

We can find the value of XY

Step-by-step explanation:

ABCD is similar to WXYZ

we know both the perimeters so lets assume they are:

ABCD=60

WXYZ=80

From the perimeters we can find the ratio of the two polygons

60/80= 3/4

since BC is similar to XY then

BC/XY = 30/XY = 3/4

cross multiplying will give us XY= 40

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
