which statement is the contrapositive of p ? p: if two angles are complementary, then the sum of their measures is 90
Over [174]

Answer:  If the sum of the measures of two angles is not 90°, then they  are not complementary angles.

<u>Step-by-step explanation:</u>

Contrapositive of p → q    is    ~q → ~p  where p is the hypothesis and q is the conclusion.

Hypothesis (p) = Two angles are complementary

                  ~p = Two angles are not complementary

Conclusion (q) = The sum of their measures is 90°

                  ~q = The sum of their measures is not 90°

~ p → ~q = If the sum of the measures of two angles is not 90°,

                then they are not complementary angles.
