Question

measure an angle to be 105 degrees why is there no complementary angle for the angle you measured?

 

 

Answer 1

Two angles are complementary if they add up to 90 degrees.

If an angle is 105 degrees, it is impossible to find another angle to add to it to give you 90 degrees. Note that angles cannot be negative.

(i.e. 90 - 105 = -15, and there is no such thing as -15 degrees)
