Answer:
1.25 would be the leading coefficient
Step-by-step explanation:
Leading coefficients in scientific notation have to be more than 1, and less than 10. Therefore, 12.5 or 0.125 would not be correct answers as they do not fit the criteria. Only 1.25 would work as the leading coefficient.
Coordinates of the midpoint are (-5.5, 5)
18m
Since the given traingles are similar
We get
Hence the distance across river is 18m
