Answer:

x = 10

Step-by-step explanation:

∵ Both angle ∠A and are corresponding angles.

∠A = ∠B

9x - 40 = 3x + 20

9x = 3x + 20 + 40

9x - 3x = 20 + 40

6x = 60

x = 60/6

x = 10

Answer:

Option A

Step-by-step explanation:

A'B' is 1/2 times the AB as the scale factor is 1/2.

<u>Find the length of AB using distance formula.</u>

AB = $\sqrt{(4 - 2)^2 + (4-0)^2} = \sqrt{20} = 2\sqrt{5}$

A'B' = 1/2*2 $\sqrt{5} = \sqrt{5}$

Correct choice is A
