Tow angles are complementary if their sum is 90 degrees.

Two angles are supplementary if their sum is 180 degrees.

anonymous · Answer

No trigonometry needed.

The complement of a 40.6 degree angle is 90-40.6 = 49.4 degrees.

anonymous · Answer

uhh ok ..

anonymous · Answer

Same procedure for the supplement of an angle.

anonymous · Answer

30°
x+30°=90
x=30°-90°
x=60°
complementary

anonymous · Answer

like this??

anonymous · Answer

Yes, or just subtract the angle from 90 (or from 180 in the case of the supplement of the angle).

anonymous · Answer

That is, the complement of any angle, x, is just 90 - x.
The supplement of any angle, y, is just 180-y.

anonymous · Answer

30° 
x+30°=180 
x=30°-180° 
x=150°
supplementary

anonymous · Answer

x = 180 - 30  (not 30 - 180)
