This questionn.. plz plz plz plz plz

1mile equals approximately 1.6 kilometers. which best approximates the number of miles in 6 kilometers?

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

1. ∠1 is complementary to ∠2 and ∠3 is complementary to ∠2. subtraction property of equality 2. m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90 substitution 3. m∠1 + m∠2 = m∠3 + m∠2 definition of complementary 4. m∠1 = m∠3 given
