Pentagon PQRST is a scale drawing of pentagon ABCDE. All side lengths of pentagon ABCDE are 5 except side BC is 6. All side lengths of pentagon PQRST are 2.5 except side QR is labeled x.
What is the value of x?

x = 3

Step-by-step explanation:

Pentagon PQRST is a scale drawing of pentagon ABCDE.

Therefore, scale factor =

                                       = Or

Ratio of the sides will be same,

x = ≈ 3

Therefore, x = 3 will be the answer.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
