Let angle 1, angle 2, and angle 3 have the following relationships.

1 answer:

3 0

180 degrees

Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.

The sample space has 36 possible pairs from 1,1 1,2 1,3 up to 6,5 and 6,6

(a). Three pairs add to 4 1,3 2,2 and 3,1 so P(4) = 3/36 = 1/12

(b). 6 pairs add to 7 so P(7) = 6/36 = 1/6

(c) 15 pairs add to less than 7 so P(<7) = 15/36 = 5/12

Stephen and Diana are traveling towards each other from points that are 276 miles apart. If Diana is traveling 4 mph faster than

Allisa [31]

Answer:

Step-by-step explanation:

let speed of Stephen=x mph

speed of Diana=x+4

then

6x+6(x+4)=276

divide by 6

x+x+4=276/6=46

2x=46-4=42

x=42/2=21

Stephen is traveling at 21 mph.

Diana is traveling at 21+4=25 mph.

A rubber ball is dropped onto a hard surface from a height of 8 feet, and it bounces up and down. At each bounce it rises to 90

Setler [38]

A. 8 feet * 0.9 = distance after first bounce
h(n) = 8 * 0.9^n

b. 8 * 0.9^14 = 1.83 feet to 2 d.p.
1.83 * 12 = 21.96 inches
