What is the missing step in the given proof? Statement: m∠4 = m∠15 Reason: Substitution Property of Equality Statement: m∠4 + m∠8 = 180° Reason: definition of supplementary angles Statement: ∠7 and ∠8 are supplementary. Reason: Linear Pair Theorem Statement: m∠4 = m∠16 Reason: Transitive Property of Equality Statement: ∠15 and ∠8 are supplementary. Reason: Transitive Property of Equality

Step-by-step explanation:

The two photos are attached for the missing information in your question.

Statement: m∠7 and m∠8 are supplementary.

Reason: Linear Pair Theorem

Statement: <7 and <8 are supplementary. Reason: Linear Pair Theorem

step-by-step explanation:

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
