Answer:
Step-by-step explanation:
You need to pay very close attention to the triangle similarity statement. This says that triangle NML is similar to triangle NVU. But if you look at the way that triangle NVU is oriented in its appearance, it's laying on its side. We need to set it upright so that angle N is the vertex angle, angle V is the base angle on the left, and angle U is the base angle on the right. When we do that we see that sides NV and NM are corresponding and exist in a ratio to one another; likewise with sides VU and ML. Setting up the proportion:

Filling in:

Cross multiply to get
324 = 108x
and x = 3
The answer is B. Multiply both sides of the top equation by 2.
This is because if you multiply 3x by 2, you get 6x, and 6x is in the other equation, which makes the x-values equal
