Answer:
39 degrees
Step-by-step explanation:
A triangle sums up at 180 degrees.
Therefore, 102+39=141.
Subtract 180 by 141 and you get 39!
To know if your answer is correct, add all angles and
make sure to get 180 in total!
2/3
Distance MS = √[(6-(-3))²+(3-3)²]= 9
Distance M'S' = √[(4-(-2))²+(2-2)²] =6
scale factor = |M'S'| /|MS|= 6/9 = 2/3
