Answer:

Step-by-step explanation:
Hello there!
We can solve for x using law of sines
As we can see in the image a side length divided by sin ( its opposite angle) = a different side length divided by sin ( its opposite angle)
So we can use this equation to solve for x

Our objective is to isolate the variable using inverse operations so to get rid of sin (65) we multiply each side by sin (65)

we're left with

assuming we have to round the answer would be 33.18 or 33.2
