lets rotate it that way, its keep rotating it i can keep it press thats better alright ,thats looks about right so, one side, is that zero mark and then my angle my other side are if there is a way points 2 looks like pretty cause to the 20˚ mark so i would type the range of the screen you are seeing that and that is the right answer and we can get the other angle so lets,try the measure this one right over here so,once again place the center of the protractor at the center at the vertex of an angle we can place the zero degree the base of the protractor at this side of the angle so we should rotate it a little bit we want to do one more time that , looks about right and the angle is now opening up this is the other side of point to 110 degrees is this larger than 90 degree its also an obtuse angle. the last one is an acute angle,this is obtuse angle 110 degrees more than 90 degrees,we typed in i got the right answer just do couple of more than these so,once again put the center the protractor at the vertex of an angle now i want to rotate it ,there we go, and this looks liking roughly an 80 degree angle but,if i am really precise 81 or 82 degrees and 80 is my best guess
