The Pentagon's ABCDE & PQRST are similar find the length X of QR Please help I will give 50 points and give branliest

x = 3.2

Step-by-step explanation:

Since they are similar the ratio of the side lengths must be the same

Using the bottom side and the unknown side from the left figure and the right figure

5            4

=

4            x

Using cross products

5x = 4*4

5x = 16

Divide by 5

x = 16/5

x =3.2
