Question

Which measurement is the measure of an obtuse angle?

75°
87°
137°
90°

Answer 1

obtuse angles are angles more than 90 degrees.
137 degrees is more than 90

Answer 2

an obtuse angle is angle that is more then 90 degrees
right angles are exactly 90 degrees
and acute angles are less then 90 degrees
so the obtuse angle would be 137 degrees
