Final answer:
Rajani's statement is incorrect because the sum of a 43 degree angle and a 37 degree angle is 80 degrees, not 90 degrees. Hence, the real complementary angle to a 43 degree angle should be 47 degrees, not 37 degrees.
Step-by-step explanation:
In Geometry, two angles are considered complementary if their degree measures add up to 90 degrees. If we evaluate Rajani's claim that an angle of 43 degrees has a complementary angle of 37 degrees, we can add the two angles together. Adding, 43 degrees + 37 degrees, we get 80 degrees instead of 90 degrees.
Therefore, the statement made by Rajani is incorrect. The complementary angle of 43 degrees should be 47 degrees (because 43 degrees + 47 degrees = 90 degrees), not 37 degrees.
