An acute angle
180 degrees in a triangle 180 - 90 - 55 = 35 35 degrees
Complementary angles total 180 degrees. So if the obtuse angle is 145 degrees, the acute angle is 35 degrees.
A complement of an acute angle must be an acute angle. An acute angle is an angle whose measure is more than 0 degrees but less than 90 degrees. For example, even if the angle was the minimum 1 degree, the complement is still 89 degrees, which is still acute. Therefore, any combination of a complement of an acute angle MUST be acute.
An angle of 60 degrees is an acute angle
