Answer:
56
Step-by-step explanation:
The angle sum theorem *I think* is that for an n-sided shape, the total sum of its angles is 180(n-2).
The sum of a triangles' angles is 180 degrees.
Therefore 4v-44 = 180.
v - 11 = 45
v = 56 degrees
Note: always check if the answer makes sense

Answer: 
Step-by-step explanation:
Use the formula for calculate the distance between two points:

Calculate the distance AB. Substitute the coordinates into the formula. Then:


Calculate the distance A'B'. Substitute the coordinates into the formula. Then:


As you can see, the distance A'B' is the distance AB multiplied by 1/2. Therefore, this is the scale factor.
