Step-by-step explanation:
4 12 13 triangle
Obtuse scalene triangle.
Sides: a = 4 b = 12 c = 13
Area: T = 23.894
Perimeter: p = 29
Semiperimeter: s = 14.5
Angle ∠ A = α = 17.839° = 17°50'19″ = 0.311 rad
Angle ∠ B = β = 66.782° = 66°46'55″ = 1.166 rad
Angle ∠ C = γ = 95.379° = 95°22'46″ = 1.665 rad
Height: ha = 11.947
Height: hb = 3.982
Height: hc = 3.676
Median: ma = 12.349
Median: mb = 7.517
Median: mc = 6.144
Inradius: r = 1.648
Circumradius: R = 6.529
Vertex coordinates: A[13; 0] B[0; 0] C[1.577; 3.676]
Centroid: CG[4.859; 1.225]
Coordinates of the circumscribed circle: U[6.5; -0.612]
Coordinates of the inscribed circle: I[2.5; 1.648]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 162.161° = 162°9'41″ = 0.311 rad
∠ B' = β' = 113.218° = 113°13'5″ = 1.166 rad

Answer: $17.50
Step-by-step explanation:
30 divided by 12 equals 2.5 therefor you would multiply 2.5 by the number of cans purchased, in this case 7.
In order: 6, 6, 12
1st: l x w | 3 * 2
2nd: 1/2(l x w) | 1/2(12)
3rd: 1st + 2nd | 12
Answer:
x = 11
The value "11" makes the equation true.
2 ( x - 5 ) = 12
2 ( 11 - 5 ) = 12
2 ( 6 ) = 12
12 = 12
