-6 and -7 because they equal -13
Answer:
(a) 180°
(b) 180°
(c) substitution property
(d) m∠3
(e) ∠3
Step-by-step explanation:
Definition: Two angles are supplementary if they add up to 180°
Proof:
By definition of supplementary angles, m∠1 + m∠2 = 180° (a) {∠1 and ∠2 are supplementary - given}
and m∠2 + m∠3 = 180° (b) {∠2 and ∠3 are supplementary - given}
Then, m∠1 + m∠2 = m∠2 + m∠3 by the substitution property (c)
Subtract m∠2 from each side. You get m∠1 = m∠3 (d)
or ∠1 ≅ ∠3 (e)
