I feel like there is something missing from this question, for example how large is the tree house? If these are just plain measurements, then I would opt for B.
3qt=2.83906L and 15lb=6.80389kg and 7L=7.39682qt hope this help
They are corresponding angles. Corresponding angles have equal measures.

The Correct choice is B. Vertical
<u>V</u><u>ertical</u> Angles have each of the pairs of opposite angles made by two intersecting lines .
