Yes. Every triangle with an obtuse angle must have two acute angles.
Not every triangle has to have an obtuse angle.
A reflex angle
A 110 degree angle is obtuse.
An angle between 90 and 180 degrees.
179.99 degrees
An obtuse angle is any angle that's measurement is between 90 and 180 degrees. This type of angle lies in the second quadrant.
179 degrees
Any obtuse angle has.
no
Complementary angles total 180 degrees. So if the obtuse angle is 145 degrees, the acute angle is 35 degrees.
