Answer:
<BCD = 128, <ECD = 52
Step-by-step explanation:
(3x + 5) + (x + 11) = 180
4x + 16 = 180
4x = 164
x = 41
<BCD is complimentary to <ACE which is (3x + 5). (3 * 41 + 5) = 128
<ECD is complimentary to <ACB which is (x + 11). (41 + 11) = 52.
Answer:
Step-by-step explanation:
m∠2 ≅ m∠7 [Alternate exterior angles]
m∠7 + m∠8 = 180° [Linear pair theorem]
m∠2 + m∠8 = 180° [Substitution property]
∠2 and ∠8 are supplementary [Definition of supplementary angles]
