Which equations for the measures of the unknown
angles x and y are correct? Check all that apply.
x=cos-1(a/c)
x=sin-1(c/b)
x= tan-1(c/a)
y=sin-1(a/c)
y = cos-1(c/b)

43

step-by-step explanation:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

27 +27 or 27times 2=54

the diffrence is 0
