Adding together the shorter two sides results in 17 m. If these two sides were laid end to end, the sum of their sides (17 m) would be less than the length of the third side. Thus, NO triangle could be constructed with this set of line segments.
Answer:
The temperature had a 6 degrees increase.
50 + (.75 x d)
D = distance traveled by in miles
keeping in mind that any line parallel to MN will have the same exact slope as MN's.
