Answer:
30, 85, 95, 150
Step-by-step explanation:
The angles of a quadrilateral add to 360
Let x be the smallest angle
x+55
x+65
x+120 are the other three angles
Add the 4 angles together and they sum to 360
x+x+55 x+65+ x+120 = 360
Combine like terms
4x+240 = 360
Subtract 240 from each side
4x+240-240 = 360 -240
4x = 120
Divide by 4
4x/4 = 120/4
x = 30
x+55= 30+55 = 85
x+65 = 30+65 = 95
x+120 = 30+120 = 150
First, you find the circumference of the full pizza.
C=d * pi
C=6pi
Then you divide it by two, because it is half of a pizza.
C=3pi
Therefore, the arc length of the crust of half a pizza is 3pi inches.
Answer:
2:6=2/6=1/3=1:3
12:48=12/48=1/4=1:4
15:30=15/30=1/2=1:2
8:24=8/24=1/3=1:3
12:18=12/18=2/3=2:3
