Answer:
90
Step-by-step explanation:
18:
18*1=18
18*2=36
18*3=54
18*4=72
18*5=90
18*6=108
45:
45*1=45
45*2=90
45*3=135
Therefore, 90 is the correct answer
Answer:
5/9
Step-by-step explanation:
You put the total amount of blue marbles over the total number of marbles and you get 15/27, which simplifies to 5/9
Sin(theeta) = square root(3)/2
theeta = sin inverse [square root (3)/2]
theeta = 60 degrees
as seen from trignometric table
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
take the square root of both sides
+ - 13 = c
