The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.
The answer will be All non-negative real numbers less than or equal to 18
because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".
Try this suggested solution, note, 'D' means the region bounded by the triangle according to the condition. It consists of 6 steps.

A triangle have 180 degrees, 44°+75° is 119°, if u want the AC degree it’s 180°-119° so the answer is 61
