-(x-3)(x-2)
The missing statements and reasons to proof that ∠1 is supplementary to ∠3 are:
- R2: Definition of corresponding angles
- R3: Corresponding angles postulate
- R5: Supplement Postulate
- S7: m∠1 + m∠3 = m∠2 + m∠3
- S8: m∠1 + m∠3 = 180° (∠1 is supplementary to ∠3)
<h3>What are Supplementary Angles?</h3>
- Supplementary angles, when added together will give us a sum of 180°.
- Linear pair angles and corresponding angles are supplementary.
Thus, to prove that ∠1 is supplementary to ∠3:
We are given that lines m and n are parallel.
∠1 and ∠3 are corresponding angles.
So therefore, ∠1 = ∠3 by the corresponding angles postulate.
∠2 and ∠3 are linear pair, their sum therefore equals 180° based on the definition of supplementary angles.
Based on the substitution property, we have the following:
m∠2 + m∠3 = m∠1 + m∠3
m∠1+m∠3=180°
Therefore, ∠1 is supplementary to ∠3 based on the definition of supplementary.
The missing statements and reasons to proof that ∠1 is supplementary to ∠3 are:
- R2: Definition of corresponding angles
- R3: Corresponding angles postulate
- R5: Supplement Postulate
- S7: m∠1 + m∠3 = m∠2 + m∠3
- S8: m∠1 + m∠3 = 180° (∠1 is supplementary to ∠3)

Answer:
-2.8 = x
Step-by-step explanation:
-7х – 10 = 18 + 3x
+7x. +7x
-10. = 18+ 10x
-18. -18
-28. = 10x
/10. /10
-2.8 = x
Well x=19/3
Decimal form is 0.6333333....
