Answer: x= 30ft y=18ft z=21ft
Explanation: based off the question u can assume that all the answers will increase the same as from what 18 went to 27 which is 9
So 9ft plus 9 = 18ft
12+9 = 21ft
21ft+9= 30ft
If that helps. That’s all I can retrieve from this questions haven’t seen these in a while haha.
