Okay, so what we have here is a geometry problem.
00:03
We're dealing with a circle.
00:04
I forgot to point, with the center at point o here, we want to find each of these letters, e, f, g, and h.
00:11
First one, the easy one is the e here.
00:14
Because of this being 134 degrees right here, that makes this 180 for a linear pair.
00:20
So it means angle e here, it's going to be 180 minus 134.
00:26
So i subtract those two, and i get 46.
00:30
Now, e is an inscribed angle with this arc, which means inscribed angle is half of the arc.
00:38
So if i take e times 2, so 46 times 2, that's going to give me 92 degrees here.
00:45
So that is this angle here.
00:47
Since o is a central angle, or so, sorry, since o is the center point, that makes f a central angle...
