let me get it a little clearer might look like that if it was a right angle, then this line over here would be, would look something like that it would be completely upright relative to this, if this were the ground. but we don't see that this orange ray over here is actually opened out wider it's opened up wider so it is obtuse. it is obtuse so this kind of comes from the actual everyday meaning acute means very sharp or very sensitive obtuse means not very sharp or not very sensitive. you could imagine this looks like a sharp point or it's, it's not opening up much. so maybe it's more sensitive to you know, relative to other things
