Complete the paragraph proof.
given: angle 1 and
2 are supplementary, and angle 2 and angle 3 are supplementary.
prove: angle 1 is equal to angle 3
by definition of supplementary angles, m_1 + m22 = _ (a) and m_2 + m_3 =)
then, m_1+m_2 = m_2+m_3 by ). subtract m_2 from each side. you get m_1= (d), or angle )

(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)

(a) 180°

(b) 180°

(c) transitive property of equality

(d) m∠3

(e) ∠3

Step-by-step explanation:

Given : ∠1 and ∠2 are supplementary and ∠2 and ∠3 are supplementary,

Prove : ∠1 ≅ ∠3 ,

By the definition of supplementary angles,

m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°,

Then,  m∠1 + m∠2 = m∠2 + m∠3 by the transitive property of equality,

Subtract m∠2 from each sides,

m∠1 = m∠3,

or ∠1 ≅ ∠3

Hence, proved

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
