Answer:

27. Alternate exterior angles are congruent.

28. Same-side interior angles are supplementary.

Step-by-step explanation:

27. The two angles whose measures are set equal by the equation are on opposite sides of the transversal, so are "opposite." They are "outside" the space between the parallel lines, so are "exterior." These descriptors identify the angles as "opposite exterior" angles. The theorem/postulate that lets you set their measures equal is ... [the one written above].

28. The two angles whose measures are added in the equation are on the same side of the transversal, so are "same-side" angles. They are "inside" the space between the parallel lines, so are "interior." These descriptors identify the angles as "same-side interior" angles. The theorem/postulate that says their measures sum to 180° is ... [the one written above].

V / -0.8 +14=39 plssss help this is literally so hard ​
Nat2105 [25]
<h2><u>Answer:</u></h2><h2> \boxed{\boxed{\sf~v=-20}}</h2><h2 /><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Subtract 14 from both sides:</h3>
  • 14-14= Cancels Out
  • 39-14=25

<em>  - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>

<u>Equation at the end of Step 1: </u>

  • v ÷ -0.8=25

<h3>2.) Multiply both sides by −0.8:</h3>
  • -0.8 × -0.8= Cancels Out
  • 25 × -0.8=-20
