Answer:
B. 27°
Explanation:
A complementary angle is an angle that measures 90°.
You can remember that because 'Complementary' starts with a 'c' and the number '9' sort of has a 'c' in it. :)
It says what the measurement of an angle that is complementary, and it gives you the measure of one part of the WHOLE 90°.
Soo... You could do this 2 ways. Either you could take 90 and subtract all the numbers or angles given, and see if you get "63°".... OR you could take 63° and add all the angle choices till you get the 90° degrees you want. Because 90°, again is complementary.
WORK: ↓↓↓
63° + 27° = 90°
