उत्तर
Complementary Angles: Two angles, the sum of whose measures is 90°, are called complementary angles.
Thus, angles ∠BAX and ∠XACare complementary angles, if
x +y = 90°
Example 1:
Angles of measure 50°and 40°are complementary angles, because
50°+40° =90°
Example 2:
Angles of measure 60°and 30°are complementary angles, because
60°+30° =90°
