Answer:
TW = 37
Explanation:
since parallelograms always have 2 pairs of parallel sides, you can assume that TW and UV are equal to each other
so you can set the equation to 2z - 37 = z
subtract z from both sides: z - 37 = 0
add 37 to both sides: z = 37
your answer is 37
to check your answer you can plug in z to 2z - 37
2(37) - 37
74 - 37
37
