Answer:
Step-by-step explanation:
B = { x, y } = { } , { x }, { y }, { x, y }
C = { 1, 2, 8 } = { } , { 1 }, { 2 }, { 8 }, { 1, 2 }, { 1, 8}, { 2, 8}, { 1, 2, 8}
. E = { a } ={ } , { a }
2. { }, {x}, {y}, {x,y}
3. { }, {1}, {2},{8},{1,2},{1,8},{2,8},{1,2,8}
4. { }, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,c,d}, {a,b,d}, {b,c,d}, {a,b,c,d}

P = 70 mi A = 210 mi^2
Sides:
a = 29 m
b = 20 m
c = 21 m
Angles:
A = 90 °
B = 43.6028 °
C = 46.3972 °
Other:
P = 70 m
s = 35 m
K = 210 mi^2
r = 6 m
R = 14.5 m
Agenda:
A = angle A
B = angle B
C = angle C
a = side a
b = side b
c = side c
P = perimeter
s = semi-perimeter
K = area
r = radius of inscribed circle
R = radius of circumscribed circle
SSS is Side, Side, Side
Heron’s formula says that if a triangle ABC has sides of lengths a, b, and c opposite the respective angles, and you let the semiperimeter, s, represent half of the triangle’s perimeter, then the area of the triangle is
f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)
Profit is the difference between revenue (17.12c +5.40(.5c)) and cost(14.56c+1.20(0.5c)). That difference is expressed by the function shown above.
