Answer:

4.

Step-by-step explanation:

If you look at the sides of the triangle, the first one has sides that have values of 10, 18, and 11.

Look at the sides of the second triangle, the values are 40, 72, and 11.

If you look at the common factors of each of these numbers, you'll see that 4 is a common factor, and the length/value of each of the sides of the 1st triangle is multiplied by 4 to get the length/value of the sides of the 2nd triangle.

18 x 4 = 72

11 x 4 = 44

10 x 4 = 40

Therefore, the scale factor is 4.

it 4 bc 10 times 4 is 40; 11 times 4 is 44; and 18 times 4 is 72 ☺️
