Assuming you mean 30 degrees per side, 60 inclusive. It certainly could be but that is not desirable unless you are cutting (milling) brass or similar. If you have an edge that obtuse you should correct it.
It cuts paper. Sure, maybe it has a burr ... but it's the way they come from the factory. Who knows, maybe ~ 25°
I'm certainly not capable of judging with my eyes...but just look at the reference image and visualize the tangent.
BTW ... if you're a MacOS user ... the ° symbol is: OPT + SHIFT + 8
