$$ m \angle A + m \angle B = 90 $$ To determine which statement is correct regarding complementary angles, we need to recall the definition of complementary angles: two angles are complementary if the sum of their measures is $$90^\circ$$. 1. **None of these**: This option is not valid unless all other options are incorrect. 2. **$$ m \angle A + m \angle B = 90 $$**: This statement is correct because it directly reflects the definition of complementary angles. 3. **If $$ m \angle A = 72^\circ $$, then $$ m \angle B = 37^\circ $$**: This statement is incorrect. If $$ m \angle A = 72^\circ $$, then $$ m \angle B $$ should be $$ 90^\circ - 72^\circ = 18^\circ$$, not $$37^\circ$$. 4. **Then $$ m \angle B 
eq 75^\circ $$**: This statement is true because if $$ m \angle A = 72^\circ $$, then $$ m \angle B $$ cannot be $$75^\circ$$ as it would not satisfy the complementary condition. Given these evaluations, the correct answer is: **$$ m \angle A + m \angle B = 90 $$**.

10 points Suppose \( \angle A \) and \( \angle B \) are complementary. Which of the following is correct? None of these \( m \angle A+m \angle B=90 \) If these If \( m \angle A=72^{\circ} \), then \( m \angle B=37^{\circ} \), then \( m \angle B \neq 75^{\circ} \)
