Final answer:
Using the properties of midsegments, HE is half the length of TV, which is 70. There seems to be a typo since 70 isn't an option, hence the closest correct answer can be assumed to be 72.
This correct answer is b)
Step-by-step explanation:
The question involves finding the length of HE, where E, D, and H are midpoints of the sides of a quadrilateral ATUV. Given UV = 116, TV = 140, and HD = 116, by the properties of midsegments in a quadrilateral, HE is half the length of TV since E and H are midpoints of ATVU. Therefore, HE = 140/2 = 70.
However, there is no option for 70 in the choices provided, suggesting there might be a typo in the question or options. Nonetheless, the closest answer would be 72, choice b.
This correct answer is b)
