Answer:
(1) x(2/3) = y
(2) 27
(3) 8
(4) 9
Step-by-step explanation:
The first line of the table tells you how to fill in the second line. Use the x and y values from the third line to write (y/x) = (2/3). This gives you the equation ...
x(2/3) = y . . . . line (1)
For the remainder of the table, you can use the given value compared to the value in line 3 to see what the multiplier is for the other value.
(2): The multiplier is 18/2 = 9, so the missing x-value is 3×9 = 27.
(3): The multiplier is 12/3 = 4, so the missing y-value is 2×4 = 8.
(4): The multiplier is 6/2 = 3, so the missing x-value is 3×3 = 9.

Answer:
33 degrees
Step-by-step explanation
I used arcos, ∠A = arccos((a2 + b2 - c2)/2ab)
= 0.5795 rad = 33.203° = 33°12'11"
