First, determine the distances from the towns.
Town A to Town B: Opposite angle C
d = sqrt ((12 - 7)^2 + (9 - 9)^2)
d = 5
Town B to Town C: Opposite Angle A
d = sqrt ((7 - 1)^2 + (9 - 1)^2)
d = 10
Town A to Town C: Opposite Angle B
d = sqrt (12 - 1)^2 + (9 - 1)^2)
d = 13.6
The angle with largest measure is the one opposite the greatest distance. Thus, the arrangement would be: C, A, B.
Each side is 52 cm. because equilateral triangles have equal lengths on each side. <span />
I think it’s 61, I’m sorry if I get it wrong. Not a 100% sure
I think letter A because on area you multiply the outside but if you’re doing perimeter you do the inside.
