Can someone help me with my question? I don’t understand how to do this.

As we can see by the 60 degree mark at angle C, we know this is a 30-60-90 triangle. I have attached an image of the relationship for a 30-60-90 triangle.

Using the example of y = 1, we can see that x the other leg of the triangle would be y.

So, x is equal to y, which we got from using the relationship shown in the attached image. The correct answer is the fourth option.

Hope this helps! :)

what level of math? also i don't need to be paid if i can you.
