Can someone with this question? (connexus, u5l4) in the figure, what is the value of x?

I THINK THE CORRECT ANSWER IS 45

So, let's pretend that there was 4 of those around the whole circle.

This would then make it look like a cube, right. And sense this would be the case, this circle would be a 360 degree, and this, we would do, 360 divided by 4, and this therefore, we could then conclude that this would be 90 degrees.

x = 90
