In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving that lines
ohaa [14]

Answer:

See the proof.

Step-by-step explanation:

<u>Statement     </u><u>                                                         </u><u>   Reason</u>

1.∠1 and ∠2 are supplementary angles     ---           Given  

2. m∠1 + m∠2 = 180°     ---                  Linear pair, they are supplementary                                

3. m∠1  and m∠3 are supplementary angles --  m∠1 + m∠3= 180

                                                                              (Supplementary angles add upto 180 degrees)  

4.  m∠1 and m∠3           ------                                 Exterior sides in opposite rays

5.   m∠1 + m∠2 = m∠1 + m∠3  ------                       Transitive property  

6.    m∠2 = m∠3                     --------------                Subtraction  property

7.   l || m  ------------- If two lines are cut by transversal the alternative interior

                               angles are the same, then the lines are paralle.

Thank you.

Gloria had two sets of alphabet cards (A–Z). She mixed the two sets together to form a single stack of cards. Then Gloria drew t
grin007 [14]
She has 52 card all together so she has a probability of drawing on the first draw 4 L's or R's because their are two sets of alphabet cards.  So that is 4/52 or 1/13 to the lowest term.  Second turn she only has 51 cards to draw from and still has 4 L's and R's so that would be 4/51 and on the third try she has only 50 cards left so that would be 4/50 or 2/25 to the lowest term.  Now multiply all three factions 1/13 x 4/51 x 2/25 = 8/16575 meaning out of the three draws she has a probability of getting a L or R, 8 out of 16575 each draw.
