Answer
Angle ACE is a complementary angle with respect to angle ACF.
Step-by-step explanation
Two angles are called complementary angles when they sum up to give 90 degrees.
From the image attached, we can see that Angle ACF = 44.8 degrees.
So, the angle that tops that up and sum up to give 90 degrees is Angle ACE which is 45.2 degrees.
44.8 + 45.2 = 90
