If you mean endpoints (-1, -3) and (11, -8) then by using the distance formula the length between the points is 13 units
Using the distance formula the length of ab is 5 units
The answer depends on what AB is and, since you cannot be bothered to provide that information, I cannot give a sensible answer.
Suppose ABC is a triangle. There is nothing in the question that requires the triangle to be right angled. Suppose AB is the side opposite to angle C and BC is a side adjacent to angle C. Then AB/BC = sin(C)/sin(A)

I assume the corresponding sides are AB and EF, and EF is a side of the larger (second) triangle. scale factor 3 means each length of the second is 3 times as long as the first. ⇒ if AB = 6 units, EF = 3 x 6 units = 18 units.
Length AB is 17 units
The length of ab can be found by using the Pythagorean theorem. The length of ab is equal to the square root of (0-8)^2 + (0-2)^2 which is equal to the square root of 68. Therefore, the length of ab is equal to 8.24.
