The two triangles are similar to each other. How long is the side labeled “?”

1 answer:

8 0

Answer:

Step-by-step explanation:

The smaller triangle seems to have dilated and formed the larger triangle. So, let's find the factor of increase.

9 / 3 = 3, so 3 is the factor of increase.

Now we need to do 4 x 3 = 12

So, ? = 12

Hope that helps!
