Answer:
y= 155.45 cm
Explanation:
To solve this, we will need to use the Law of Sines
This states that:

Firstly, we need to find the sin of angle y. As this is a 30-60-90 right triangle, we know that the angle must be 60 degrees
Now that we have side x, the angle X, and the angle Y, we can solve for the side y using the Law of Sines
Lets plug in our known values into the equation

Next we can solve for y

When plugged into a calculator, you get the value of 155.45 cm for side y
Do a ratio dude:
12.2 19.5
------- = ------
200 x
Solve, and you get that x is approx equal to 320 mg.
