Please need help on this one not even sure on this

I‘m pretty sure its a special right triangle, basically a 30, 60, 90 triangle. I checked with the formula and it’s correct. So the angle W is wither a 60 Degree or 30 degree and I‘m on the side of 30 degrees.

So I’m pretty sure its 30 degree.

The formuda is the hypotenuse is 2x and the (a) (3 in this case) is x. The 5 would come out as the formula 3. Now we know the sides, 3, 5 and 6 so we just plug it in and solve for the square root and it equals to ABOUT 5.

I’m not sure if I’m correct but I’m not confident.
