WebFeb 23, 2024 · Notice that the angle in question is obtuse (>90 degrees) Example E: Right Angles In Example D, notice that both angles in question ∠WYZ and ∠WYX are right angles, thus they are neither acute or obtuse and both have an angle measure of 90 degrees. WebOne, 60 degrees would be 2/3 of a right angle, while 30 degrees would be 1/3 of a right angle. A right angle would look something like this. So this looks much more like 2/3 of a right angle, so I'll go with 60 degrees. Another way to think about is that 60 degrees is 1/3 of 180 degrees, which this also looks like right over here.
