Given: lines l and m are parallel, and line t is a transversal.
angle pair result/justification
1 and 2 are equal (vertical angles)
6 and 8 are equal (corresponding angles)
1 and 4 are equal (alternate exterior angles)
4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)
Note:
alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.
If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)
If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)
Answer:
Cost for 50 songs: $64
Cost for s songs: s + 14
Step-by-step explanation:
Since it is $1 per song, if he downloaded 50 songs, it would be $50 extra dollars.
Add this to the monthly charge of 14:
50 + 14
= 64
So, the cost of 50 songs would be $64.
Now, find the cost for downloading s songs.
Each song is $1, so the cost can be represented by s + 14.
The answer is:
Cost for 50 songs: $64
Cost for s songs: s + 14
Answer:
108°
Step-by-step explanation:
180° - 72° = 108°
Answer:
PW = 11
Step-by-step explanation:
Given that the triangles are similar then the ratio of corresponding sides are equal, that is
= 
← substitute values
= 
( cross- multiply )
12PW = 132 ( divide both sides by 12 )
PW = 11
3 significant figures.
