If these two shapes are similar, what is the measure of the missing length b?

B = 7mm

Step-by-step explanation:

This is probably an enlargement problem.

To solve this:

the blue triangle has all of it's measurements you need. Let's start with that.

6/36 =

We know that one side, the bottom side of the green triangle is 42mm.

6/36 = b/42

We could simplify 6/36 into 1/6

1/6 = b/42

AHA! the denominators are easy! 6 times 7 is equal to 42, so 1 times 7 should equal b!

1/6 = 7/42

Check:

6/36 = b/42

36b = 6*42

36b = 252

   b = 252/36

   b = 7

So yes! B is 7 mm. Pls mark me brainliest, as I never have a single brainliest.
