If ∠K and ∠L are supplementary angles and m∠K = 56°, find m∠L.

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x

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
