Find the value of x
this is due 6pm

In SOHCAHTOA you want to use cosine (CAH)
Cos75 = x/30
Use algebra to get x by itself.
So type into your calculator:

30cos(75) which equals 7.76

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
