The reasons that the sample is representative:
The builders were chosen at random
The population included only builders who build in Vicki's town
Vickie wanted to determine the cost of building a house in her home, so the fact that the builders were from her town makes the sample more representative. Moreover, the random choosing of the builders helps to remove any biases that may be present.

Answer:
2 = 64
1 = 90
3 = 10
Step-by-step explanation:
This is one possible example, remember that sides 2 and 3 must be less the 90 degrees if not it is not applicable
All sides are the same, hence, all three angles are the same, and each one of them is 60 degrees. Due to that:
7x + 4 = 60
7x = 56
x = 56/7 = 8
8y + 12 = 60
8y = 48
y = 48/8 = 6
